    Ana Lisa Tavares and Mel Dixon: What if a treatment created for one person could transform care for thousands?
    Mar 25 2026
    In this episode, we explore how individualised medicines are evolving from “n=1” treatments (a treatment effective for a single individual) into approaches that could transform care for many people living with rare conditions. Advances in genomic medicine are making it possible to design highly targeted treatments based on an individual’s genetic information. While these therapies may begin as bespoke solutions for a single patient, they can often be adapted, refined or reused to benefit others with similar conditions. While the research is evolving, the systems needed to deliver these treatments at scale are still catching up. From regulation to access, our guests discuss what needs to change to turn this potential into reality. Our host Sharon Jones, is joined by: Ana Lisa Tavares, Clinical Lead for Rare Disease Research at Genomics England Mel Dixon, Participant Panel member and CEO and Founder of Cure DHDDS If you enjoyed today’s conversation, please like and share wherever you listen to your podcasts. “However rare your condition is, someone has a right to have hope. Everybody should have a hope that we should be able to find a treatment.” You can download the transcript or read it below. Sharon: What if treatments once designed for just one person could now help many others? Thanks to advances in genomic medicine, regulations are changing and research is expanding. This opens up more options for treatments for rare conditions. But what does this mean and how close is real change? I'm Sharon Jones, and this is Behind the Genes. We look at how genomics is changing healthcare, covering everything from cutting-edge research to real-life stories. Individualised medicines are a fast-moving area, but there's still a big gap between scientific progress and what's actually happening to patients. You could call it the gap between hype and hope. Ana Lisa: However rare your condition is, someone has a right to have hope. Everybody should have a hope that we should be able to find a treatment. Sharon: Coming up, we'll hear from Ana Lisa Tavares, Clinical Lead for Rare Disease Research at Genomics England, and Consultant in Clinical Genetics at Cambridge University Hospital, as well as Mel Dixon, member of the Participant Panel at Genomics England and CEO and founder of Cure DHDDS. Mel opens this chat by explaining why developments in individualised healthcare really matter to her. Mel: This issue is really personal to me. I have three children, two of whom are affected with an ultra-rare DHDDS gene variant, for which there is currently no treatment. Their condition causes symptoms such as, well, it varies between mild to severe learning difficulties, seizures, tremors, and movement and coordination difficulties. But the, the most worrying thing for us was that this condition is actually also progressive. So over time it becomes more of a Parkinsonism and some patients experience dementia-like symptoms and psychosis. So for us to get a treatment that targets the genetic cause of, of their condition is, like, the most important thing in, in our lives. If we could intervene now, they could potentially, at the stage they're at, you know, live an independent life with, with some supports. But if the disease is left to progress, it would be a very different outcome for them. Sharon: I mean, that sounds so difficult and I can't even imagine how life is for you and your family. And I can see what is driving you to find anything to extend the life of your children and to give them that opportunity to, to have a better quality of life. And then Lisa. Ana Lisa: It's a huge burden for families to carry. And I think at the moment there's an additional layer of burden, which shouldn't fall on families, to feel like they need to forge a pathway for their child to have a chance of a treatment. That's, that's a lot to bear. Mel: I think as well, families feel they almost have to become mini scientists in their children's specific condition overnight, because you go to these appointments with the consultants and nobody's heard of the condition and they don't know, they just don't really know what to do with you. So they're asking you, you know, so tell me about this, this gene change. What, what does it do? What does it mean? So you have to become the mini professor in your child's condition to be able to advocate for them. We've had to really learn on our feet so that we're able to advocate and push for research into DHDDS, because without us doing it, nobody else was going to be. Sharon: Yeah. So that's, you know, that's partly what we're here and what this podcast is for, it's here to support families to, to understand this stuff. And Ana Lisa, can you just break it down to us, what is individualised medicines? Ana Lisa: An individualised medicine that's made for one individual person. In reality, sometimes there are other individuals that can also benefit from the same medicines, ...

  • Georgia Chan: What is de-identified data?

    Georgia Chan: What is de-identified data?
    Mar 18 2026
    In this explainer episode, we’ve asked Georgia Chan, Senior Data Wrangler at Genomics England, to explain what de-identified data is. You can also find a series of short videos explaining some of the common terms you might encounter about genomics on our YouTube channel. If you’ve got any questions, or have any other topics you’d like us to explain, let us know on podcast@genomicsengland.co.uk. You can download the transcript or read it below. Florence: What do we mean by de-identified data? My name is Florence Cornish, and today I'm here with Georgia Chan. Georgia is Senior Data Wrangler here at Genomics England, which just means that she cleans up and adds structure to complicated data so that it becomes usable, and she is going to be telling us much more about the topic of de-identified data. Georgia, I think it would be a good place to start by talking about the National Genomic Research Library, which is the library that we at Genomics England store data in. So maybe you could explain more about that and what kind of data is in there. Georgia: Sure. Thanks Florence. So, we have genomic data. Genomic data is information that comes from a person's DNA. It helps us understand how the body works and why disease happens. This can include whole genome sequencing data, variants found in genes, small differences that make each of us unique, and information about how genes function or how they differ between people. Genomic data does not include a person's name or who they are. It's biological information, not identity, and it's used to understand health and disease. It's really important to note that by nature, it's nature, genomic information is incredibly rich. We all have millions of common genetic variants, but your whole genome is unique to you. So although genomic data alone can't directly identify you, it still counts as personal data under data protection. We also have clinical data. Clinical data provides real world context for the genomic data. It shows what's happening in someone's health. This can include diagnosis of a disease or a symptom, treatments that have been received, health outcomes over time, such as remission or progression, and this clinical data that help researchers see how genetic differences relate to symptoms, treatment response, and long-term outcomes. So, we have both of these kinds of data. Genomic data on its own can be hard to interpret, and clinical data on its own only tells part of the story. Together, they allow researchers to better understand how diseases develop, helps them discover new or more targeted treatments, and it helps them improve diagnosis, care, and outcomes. And this is why both types of this data are used together in the National Genomic Research Library. Florence: And so, both of these data types, both clinical and genomic, we say that they are de-identified. But what exactly does that mean? Georgia: Yes, good question. De-identified data means that information which directly identifies a person has been changed or removed from a health record before researchers can access it. And in practice, it means that researchers cannot see who the person is. The data cannot be used to contact individuals, and a person's identity is protected by design, which means that necessary safeguards are embedded into every stage of a service or process. So, researchers work with the data, but not with people's identities. Florence: Could you tell me a little bit more about why it's so important to de-identify data in this way? Georgia: Sure. De-identification creates a safe middle ground. It means that data can be used to improve healthcare whilst people's privacy and trust is respected. So, without de-identification, every new research question would require individual contact and large-scale, long-term research would be extremely difficult. With de-identification, we reduce the risk of someone being identified. We prevent inappropriate use of data, and we ensure that data is used only for approved research. And it's important to note also that it sits alongside a list of other safeguards, so that helps ensure data is used responsibly, such as secure Research Environment, strict access control, independent ethical and governance approvals. And all of those safeguards are provided in Genomics England's Research Environment. Florence: I think a common question that people might have, or a question that I definitely had when I first heard the term, is how de-identified data is different from anonymous data. Georgia: Yes, it is a good question. So, anonymised data cannot be linked back to an individual and is no longer considered personal data, whereas de-identified anonymised data, it has identified as hidden from researchers, but it can still be relinked by a trusted authorised organisation if needed. So, in healthcare research, ...

  • Amanda Pichini, Dr Katie Snape, Bev Speight, and Dr Sarah Westbury: Can blood cancer be inherited?

    Amanda Pichini, Dr Katie Snape, Bev Speight, and Dr Sarah Westbury: Can blood cancer be inherited?
    Feb 25 2026
    Blood cancers are the fifth most common group of cancers in the UK. But for a small number of people, the condition may have an inherited genetic cause. In this episode of Behind the Genes, we explore the role of genetics in blood cancer, and what an inherited risk means for patients and their families. Our guests explain what blood cancer is, how inherited factors can increase risk, and why multidisciplinary teamwork is key to supporting families. They also look ahead to future advances, from whole genome sequencing to prevention trials. Our host Amanda Pichini, Clinical Director at Genomics England, is joined by: Dr Katie Snape, Principal Clinician at Genomics England and Consultant Cancer Geneticist Bev Speight, Principal Genetic CounsellorDr Sarah Westbury, Consultant Haematologist “By doing whole genome sequencing we get all of the information about all of the changes that might have happened, we know whether any are inherited, but importantly, we’re certain of the ones that have just occurred in the cancer cells and can help guide us with their treatment.” You can download the transcript or read it below. Amanda: Hello, and welcome to Behind the Genes. Sarah: When we think about blood cancers, it’s a whole range of different conditions and when you talk to patients who are affected with blood cancers or are living with them, their experiences are often really different from one another, depending in part on what kind of blood cancer they have. We also know that blood cancers affect not just the cell numbers but also the way that those cells function, and so the range of symptoms that people can get is really variable. Amanda: I am your host, Amanda Pichini, clinical director at Genomics England and genetic counsellor. Today I’ll be joined by Dr Katie Snape, principal clinician at Genomics England and a consultant cancer geneticist in London, Bev Speight, a principal genetic counsellor in Cambridge, and Dr Sarah Westbury, and haematologist from Bristol. They’ll be talking about blood cancers and the inherited factors that increase blood cancer risk. If you enjoy this episode, we’d love your support, so please subscribe, rate and share on your favourite podcast app. Let’s get started. Thanks to everyone for joining us today on this podcast, we’re delighted to have so many experts in the room to talk to us about blood cancer. I’d love to start with each of you introducing yourself and telling us and the listeners a little bit about your role, so, Sarah, could we start with you? Sarah: Sure. It’s great to be here. My name’s Sarah Westbury, and I’m a consultant haematologist who works down in Bristol. And my interest in this area is I’m a diagnostic haematologist so I work in the laboratories here in the hospitals, helping to make a diagnosis of blood cancer for people who are affected with these conditions. And I also look after patients in clinic who have different forms of blood cancer, but particularly looking after families who have an inherited predisposition to developing blood cancer. And in the other half of my job, I work as a researcher at the University of Bristol. And in that part of my job, I’m interested in understanding the genetic basis of how blood counts are controlled and some of the factors that lead to loss of control of those normal blood counts and how the bone marrow functions and works. Amanda: Thank you. That’s really interesting, we’ll be looking forward to hearing more about your experience. Bev, we’ll come to you next. Bev: Thank you. Hello everyone, I’m Bev Speight, I’m a genetic counsellor, and I work at Addenbrooke’s Hospital in Cambridge. I work with families with hereditary cancers in the clinical genetic service, and for the last six years or so have been focused on hereditary blood cancers. So we’ve been helping our haematologists across the region to do genetic tests and interpret the results, and then in my clinic seeing some of the onward referrals that come to clinical genetics after a hereditary cause for blood cancer is found. I’m also part of the Council for the UK Cancer Genetics Group. Amanda: Thank you, Bev. And Katie, over to you. Katie: Hello, I’m Katie Snape. I’m a genetics doctor and I am a specialist in inherited cancer. So we look after anyone who might have an increased chance of developing cancer in their lifetime due to genetic factors. I am the chair of the UK Cancer Genetics Group, so that’s a national organisation to try and improve the quality of care and care pathways for people with inherited cancer risk in the UK. And I have a special interest in inherited blood cancers through my work at King’s College Hospital, I work in the haematology medicine service there seeing individuals who might have or have been diagnosed as having an...

  • Réka Novotta: What is informed consent?

    Réka Novotta: What is informed consent?
    Feb 11 2026
    In this explainer episode, we’ve asked Réka Novotta, Research Ethics Operations Manager at Genomics England, to explain what informed consent is. You can also find a series of short videos explaining some of the common terms you might encounter about genomics on our YouTube channel. If you’ve got any questions, or have any other topics you’d like us to explain, let us know on podcast@genomicsengland.co.uk. You can download the transcript or read it below. Florence: What do we mean by informed consent? My name is Florence Cornish, and today I'm here with Réka, who is Research Ethics Operations Manager here at Genomics England, and she's going to be telling us much more about it. I think it would first be helpful Réka, if you could explain the word consent. Réka: The broad definition of consent is that it's the voluntary agreement given by an individual to participate in a particular activity. We all probably give consent to a lot of different things each day without really realizing it. So, you go on to read the news in the morning, and the website asks for your consent to process cookies. You maybe go to a routine GP appointment later, and you stick your arm out for them to measure your blood pressure. Maybe you even go to a podcast and you give consent to a host to record your voice. So, these are all based on affirmative action made by you while taking into consideration the information that's available to you. The technical definition of consent often includes that it's freely given, meaning that you are not coerced. That it’s specific, meaning when you stick your arm out for your doctor, you're only agreeing to that part of the examination, and perhaps most importantly, that person needs to be adequately informed for the consent to be meaningful. Florence: So you gave lots of really interesting examples there. I think it would be good to understand what we mean by informed consent and where this distinction comes in. How does it differ? Réka: By informed consent, we mean that the person consenting has been provided with all relevant and necessary information about the activity, in a format that is accessible and understandable for them. And that latter part of the sentence is really important, because if you go to the doctor and the doctor speaks to you in French, if you speak French, then wonderful, you have all the information that you need. But if you don't, even though the information is technically there, you not understanding it makes it impossible for your consent to be informed. Similarly, if you think about maybe an older person who's not familiar with technology, if they see a QR code, they might not necessarily know what to do with it, even if it would technically lead to all of the information that they would ever want to know about Genomics England. Florence: So you mentioned Genomics England, obviously we both work for Genomics England, this is a Genomics 101 podcast. So what do we mean by informed consent in the context of genomics? Where does it come into play? Réka: So if we think about informed in a traditional research study, they test a drug, the treatment either works or it doesn't work, and there's analysis of that data, and that's sort of the end of the process. With genomics, there's a huge amount of information that gets generated and analysed, and the field itself is rapidly evolving. So we may not have an answer today, but we might do tomorrow, which puts our participants' data in the research resource that we manage in a really unique position. Because of that, it's even more important perhaps for this consent to be ongoing. Consent is often incorrectly considered a tick box exercise, where you receive information, you consider the information, you make a decision, and that's sort of it. Whereas for genomics, it's important that it is an ongoing conversation and it doesn't just stop at the signing of a form. We also employ what's called a broad consent model. Genomics England manages the National Genomic Research Library, which rather than being a single study, is a resource for a wide range of research uses. It allows us to gain permission via the informed consent conversations for the storage and the use of data and samples for upcoming studies that we don't yet know about. And this eliminates the need to reconsent each participant every time a researcher starts to use their data for a new research project, and in turn, and this also feeds back to the need for ongoing conversation, a fully informed consent is very hard to achieve at the time of consenting. Florence: So you mentioned the National Genomic Research Library, and we actually did a previous explainer podcast episode about this. So, if listeners would like to learn more about it, you can check out our previous Genomics 101 episode: What is ...

  • Adam Clatworthy, Emma Baple, Jo Wright, Lisa Beaton and Jamie Ellingford: What Does the Diagnostic Odyssey Really Mean for Families?

    Adam Clatworthy, Emma Baple, Jo Wright, Lisa Beaton and Jamie Ellingford: What Does the Diagnostic Odyssey Really Mean for Families?
    Jan 28 2026
    In this special episode, recorded live at the 2025 Genomics England Research Summit, host Adam Clatworthy is joined by parents, clinicians and researchers to explore the long, uncertain and often emotional journey to a genetic diagnosis. Together, they go behind the science to share what it means to live with uncertainty, how results like variants of uncertain significance (VUS) are experienced by families, and why communication and support matter just as much as genomic testing and research. The panel discuss the challenges families face when a diagnosis remains out of reach, the role of research in refining and revisiting results over time, and how collaboration between researchers, clinicians and participants could help shorten diagnostic journeys in the future. Joining Adam Clatworthy, Vice-Chair for the Participant Panel, on this episode are: Emma Baple – Clinical geneticist and Medical Director, South West Genomic Laboratory Hub Jamie Ellingford – Lead genomic data scientist, Genomics England Jo Wright – Member of the Participant Panel and Parent Representative for SWAN UK Lisa Beaton - Member of the Participant Panel and Parent Representative for SWAN UK Linked below are the episodes mentioned in the episode: What is the diagnostic odyssey? What is a Variant of Uncertain Significance? Visit the Genomics England Research Summit website, to get your ticket to this years event. You can download the transcript, or read it below. Sharon: Hello, and welcome to Behind the Genes. My name is Sharon Jones and today we’re bringing you a special episode recorded live from our Research Summit held in June this year. The episode features a panel conversation hosted by Adam Clatworthy, Vice-Chair of the Participant Panel. Our guests explore navigating the diagnostic odyssey, the often-complex journey to reaching a genetic diagnosis. If you’d like to know more about what the diagnostic odyssey is, check our bitesize explainer episode, ‘What is the Diagnostic Odyssey?’ linked in the episode description. In today’s episode you may hear our guests refer to ‘VUS’ which stands for a variant of uncertain significance. This is when a genetic variant is identified, but its precise impact is not yet known. You can learn more about these in another one of our explainer episodes, “What is a Variant of Uncertain Significance?” And now over to Adam. -- Adam: Welcome, everyone, thanks for joining this session. I’m always really humbled by the lived experiences and the journeys behind the stories that we talk about at these conferences, so I’m really delighted to be hosting this panel session. It’s taking us behind the science, it’s really focusing on the people behind the data and the lived experiences of all the individuals and the families who are really navigating this system, trying to find answers and really aiming to get a diagnosis – that has to be the end goal. We know it’s not the silver bullet, but it has to be the goal so that everyone can get that diagnosis and get that clarity and what this means for their medical care moving forwards. So, today we’re really going to aim to demystify what this diagnostic odyssey is, challenging the way researchers and clinicians often discuss long diagnostic journeys, and we’ll really talk about the vital importance of research in improving diagnoses, discussing the challenges that limit the impact of emerging research for families on this odyssey and the opportunities for progress. So, we’ve got an amazing panel here. Rather than me trying to introduce you, I think it’s great if you could just introduce yourselves, and Lisa, I’ll start with you. Lisa: Hi, I’m Lisa Beaton and I am the parent of a child with an unknown, thought to be neuromuscular, disease. I joined the patient Participant Panel 2 years ago now and I’m also a Parent Representative for SWAN UK, which stands of Syndromes Without A Name. I have 4 children who have all come with unique and wonderful bits and pieces, but it’s our daughter who’s the most complicated. Adam: Thank you. Over to you, Jo. Jo: Hi, I’m Jo Wright, I am the parent of a child with an undiagnosed genetic condition. So I’ve got an 11-year-old daughter. 100,000 Genomes gave us a VUS, which we’re still trying to find the research for and sort of what I’ll talk about in a bit. And I’ve also got a younger daughter. I joined the Participant Panel just back in December. I’m also a Parent Rep for SWAN UK, so Lisa and I have known each other for quite a while through that. Adam: Thank you, Jo. And, Jamie, you’re going to be covering both the research and the clinician side and you kind of wear 2 hats, so, yeah, over to you. Jamie: Hi, everyone, so I’m Jamie Ellingford and, as Adam alluded to, I’m fortunate and I get to wear 2 hats. So, one of those hats is that I’m Lead Genomic Data Scientist for Rare ...

    Sharon Jones and Dr Rich Scott: Reflecting on 2025 - Collaborating for the future of genomic healthcare
    Dec 31 2025
    In this special end-of-year episode of Behind the Genes, host Sharon Jones is joined by Dr Rich Scott, Chief Executive Officer of Genomics England, to reflect on the past year at Genomics England, and to look ahead to what the future holds. Together, they revisit standout conversations from across the year, exploring how genomics is increasingly embedded in national health strategy, from the NHS 10-Year Health Plan to the government’s ambitions for the UK life sciences sector. Rich reflects on the real-world impact of research, including thousands of diagnoses returned to the NHS, progress in cancer and rare condition research, and the growing momentum of the Generation Study, which is exploring whether whole genome sequencing could be offered routinely at birth. This episode offers a thoughtful reflection on how partnership, innovation, and public trust are shaping the future of genomic healthcare in the UK and why the years ahead promise to be even more exciting. Below are the links to the podcasts mentioned in this episode, in order of appearance: How are families and hospitals bringing the Generation Study to life?How can cross-sector collaborations drive responsible use of AI for genomic innovation?How can we enable ethical and inclusive research to thrive?How can parental insights transform care for rare genetic conditions?How can we unlock the potential of large-scale health datasets?Can patient collaboration shape the future of therapies for rare conditions?https://www.genomicsengland.co.uk/podcasts/what-can-we-learn-from-the-generation-study “There is this view set out there where as many as half of all health interactions by 2035 could be informed by genomics or other similar advanced analytics, and we think that is a really ambitious challenge, but also a really exciting one.” You can download the transcript, or read it below. Sharon: Hello, and welcome to Behind the Genes. Rich: This is about improving health outcomes, but it’s also part of a broader benefit to the country because the UK is recognised already as a great place from a genomics perspective. We think playing our role in that won’t just bring the health benefits, it also will secure the country’s position as the best place in the world to discover, prove, and where proven roll out benefit from genomic innovations and we think it’s so exciting to be part of that team effort. Sharon: I’m Sharon Jones, and today I’ll be joined by Rich Scott, Chief Executive Officer at Genomics England for this end of year special. We’ll be reflecting on some of the conversations from this year’s episodes, and Rich will be sharing his insights and thoughts for the year ahead. If you enjoyed this episode, we’d love your support, so please subscribe, rate, and share on your favourite podcast app. So, let’s get started. Thanks for joining me today, Rich. How are you? Rich: Great, it’s really good to be here. Sharon: It’s been a really exciting year for Genomics England. Can you tell us a bit about what’s going on? Rich: Yeah, it’s been a really busy year, and we’ll dive into a few bits of the components we’ve been working on really hard. One really big theme for us is it’s been really fantastic to see genomics at the heart of the government’s thinking. As we’ll hear later, genomics is at the centre of the new NHS 10-year health plan, and the government’s life sciences sector plan is really ambitious in terms of thinking about how genomics could play a role in routine everyday support of healthcare for many people across the population in the future and it shows a real continued commitment to support the building of the right infrastructure, generating the right evidence to inform that, and to do that in dialogue with the public and patients, and it’s great to see us as a key part of that. It’s also been a really great year as we’ve been getting on with the various programmes that we’ve got, so our continued support of the NHS and our work with researchers accessing the National Genomic Research Library. It’s so wonderful to see the continued stream of diagnoses and actionable findings going back to the NHS. It’s been a really exciting year in terms of research, publications. In cancer, some really exciting publications on, for example, breast cancer and clinical trials. Really good partnership work with some industry partners, really supporting their work. For me, one of the figures we are always really pleased to see go up with time is the number of diagnoses that we can return thanks to research that’s ongoing in the research library, so now we’ve just passed 5,000 diagnostic discoveries having gone back to the NHS, it really helps explain for me how working both with clinical care and with research and linking them really comes to life and why it’s so vital. ...

    Dr Katie Snape: How can genomics help us understand cancer?
    Dec 17 2025
    In this explainer episode, we’ve asked Dr Katie Snape, principal clinician at Genomics England, cancer geneticist, and specialist in inherited cancer, to explain how genomics can help us understand cancer. You can also find a series of short videos explaining some of the common terms you might encounter about genomics on our YouTube channel. If you’ve got any questions, or have any other topics you’d like us to explain, let us know on podcast@genomicsengland.co.uk. You can download the transcript or read it below. Flo: How can genomics help us understand cancer? I'm Florence Cornish, and today I'm joined with Katie Snape, who is Principal Clinician here at Genomics England, lead Consultant for Cancer Genetics at the Southwest Thames Centre for Genomics, and Chair of UK Cancer Genetics Group. So Katie, it's probably safe to say that everyone listening will have heard the word cancer before. Lots of people may have even been directly affected by it or know someone who has it or who has had it, and I think the term can feel quite scary sometimes and intimidating to understand. So, it might be good if you could explain what we actually mean when we say the word cancer. Katie: Thanks, Florence. So, our bodies are made up of millions of building blocks called cells. Each of these cells contains an instruction manual, and our bodies read this to build a human and keep our bodies working and growing over our lifetimes. So, this human instruction manual is our genetic information, and it's called the human genome. Throughout our lifetime, our cells will continue to divide and grow to make more cells when we need them. And this means that our genetic information has to contain the right instructions, which tell the cells to divide when we need new cells, like making new skin cells, for example as our old skin cells die, but they also need to stop dividing when we have enough new cells and we don't need anymore. And this process of growing but stopping when we don't need anymore cells, keeps our bodies healthy and functioning as they should do. However, if the instructions for making new cells goes wrong and we don't stop making new cells when we're supposed to, then these cells can grow out of control, and they can start spreading and damaging other parts of our body. And this is basically what cancer is. It's an uncontrolled growth of cells which don't stop when they're supposed to, and they grow and spread and damage other tissues in our body. Florence: So, you mentioned there that cancer can arise when the instructions in our cells go wrong. Could you talk a little bit more about this? How does it lead to cancer? Katie: Yeah. So the instructions that control how our cells should grow and then stop growing are usually called cancer genes. So our body reads these instructions a bit like we might read an instruction manual to perform a task. So if we imagine that one of these important cancer genes that has a spelling mistake, which means the body can't read it properly, then those cells won't follow the right instructions to grow and then stop growing like they should. So if our cells lose the ability to read these important instructions due to this type of spelling mistake, then that's when a cancer can develop. As these spelling mistakes happen in cancer genes, we call them genetic alterations or genetic variants. Florence: And so, when you're in the clinic seeing somebody who has cancer, what kinds of genomic tests can they have to help us find out a little bit more about it? Katie: So the genetic alterations that can cause cancer can happen in different cells. So that's why cancer can affect many different parts of the body. If a genetic alteration happens in a breast cell, then a breast cancer might develop. If the alteration happens in a skin cell, then a skin cancer could develop. We can take a sample from the cancer. This is often known as a biopsy, and then we can use this sample to extract the genetic information to read the instructions in the cancer cells, and when we do this, we are looking for spelling mistakes in the important cancer genes, which might of course, those cells to grow out of control. We can also look for patterns of alterations in the cells, which might tell us the processes that led to those genetic alterations occurring. For example, we can look at patterns of damage in the genetic information caused by cigarette smoke, or sunlight, or problems because the cell has lost its ability to mend and repair its genetic information. And we can also count the number of different alterations in the cancer cell, which might tell us how different that cancer cell is from our normal cells, and that can be important because we might be able to use medications to get our immune system to attack the cancer cells. So where we see genetic alterations in a cancer cell, we call them acquired or somatic alterations because we ...

Florence: What is a genetic counsellor? I'm Florence Cornish, and today I'm joined with Amanda Pichini, a registered genetic counsellor and clinical director for Genomics England, to find out more. So, before we dive in, lots of our listeners have probably already heard the term genetic counsellor before, or some people might have even come across them in their healthcare journeys. But for those who aren't familiar, could you explain what we mean by a genetic counsellor? Amanda: Genetic counsellors are healthcare professionals who have training in clinical genomic medicine and counselling skills. So they help people understand complex information, make informed decisions, and adapt to the impact of genomics on their health and their family. They're expert communicators, patient advocates, and navigators of the ethical issues that genomics and genomic testing could bring. Florence: Could you maybe give me an example of when somebody might see a genetic counsellor? Amanda: Yes, and what's fascinating about genetic counselling is that it's relevant to a huge range of conditions, scenarios, or points in a person's life. Someone's journey might start by going to their GP with a question about their health. Let's say they're concerned about having a strong family history of cancer or heart disease, or perhaps a genetic cause is already known because it's been found in a family member and they want to know if they've inherited that genetic change as well. Or someone might already be being seen in a specialist service, perhaps their child has been diagnosed with a rare condition. A genetic counsellor can help that family explore the wide-ranging impacts of a diagnosis on theirs and their child's life, how it affects their wider family, what it might mean for future children. You might also see a genetic counsellor in private health centres or fertility clinics, or if you're involved in a research study too. Florence: And so, could you explain a bit more about the types of things a genetic counsellor does? What does your day-to-day look like, for example? Amanda: Most genetic counsellors in the UK work in the NHS as part of a team alongside doctors, lab scientists, nurses, midwives, or other healthcare professionals. Their daily tasks include things like analysing a family history, assessing the chance of a person inheriting or passing on a condition, facilitating genetic tests, communicating results, supporting family communication, and managing the psychological, the emotional, the social, and the ethical impacts of genetic risk or results. My day-to-day is different though. I and many other genetic counsellors have taken their skills to other roles that aren't necessarily in a clinic or seeing individual patients. It might involve educating other healthcare professionals or trainees, running their own research, developing policies, working in a lab, or a health tech company, or in the charity sector. For me, as Clinical Director at Genomics England, I bring my clinical expertise and experience working in the NHS to the services and programmes that we run, and that helps to make sure that we design, implement, and evaluate what we do safely, and with the needs of patients, the public, and healthcare professionals at the heart of what we do. My day-to-day involves working with colleagues in tech, design, operations, ethics, communications, and engagement, as well as clinical and scientific experts, to develop and run services like the Generation Study, which is sequencing the genomes of 100,000 newborn babies to see if we can better diagnose and treat children with rare conditions. Florence: So, I would imagine that one of the biggest challenges of being a genetic counsellor is helping patients to kind of make sense of the complicated test results or information, but without overwhelming them. So how do you balance kind of giving people the scientific facts and all the information they need, but while still supporting them emotionally? Amanda: This is really at the core of what genetic counsellors can do best, I think. Getting a diagnosis of a rare condition, or finding out about a risk that has a genetic component, can come with a huge range of emotions, whether that's worry, fear, or hope and relief. It can bring a lot of questions, too. What will this mean for my future or my family's future? What do you know about this condition? What sort of symptoms could I have? What treatments or ...
