In this episode, we delve into the impact of the new groundbreaking research uncovering the RNU4-2 genetic variant linked to neurodevelopmental conditions. The discovery, made possible through whole genome sequencing, highlights a genetic change in the RNU4-2 gene that affects about 1 in 200 undiagnosed children with neurodevelopmental conditions, making it more prevalent than previously thought. This discovery represents one of the most common single-gene genetic causes of such conditions. Our host, Naimah Callachand, Head of Product Engagement and Growth at Genomics England, is joined by Lindsay Pearse who shares her journey through the diagnosis of her son Lars. They are also joined by Sarah Wynn, CEO of Unique, and Emma Baple, Clinical Genetics Doctor and Professor of Genomic Medicine in the University of Exeter and the Medical Director of the Southwest NHS Genomic Laboratory Hub. We also hear from the 2 research groups who independently discovered the findings: Dr Andrew Mumford, Professor of Haematology at the University of Bristol Link to the research paper: https://www.nature.com/articles/s41591-024-03085-5 Assistant Professor Nicky Whiffin, Big Data Institute and Centre for Human Genetics at the University of Oxford Link to the research paper: https://www.nature.com/articles/s41586-024-07773-7 To access resources mentioned in this podcast: Unique provides support, information and networking to families affected by rare chromosome and gene disorders - for more information and support please visit the website.Connect with other parents of children carrying a variation in RNU4-2 on the Facebook group. "I think one of the things we really hope will come out of diagnoses like this is that we will then be able to build up more of that picture about how families are affected. So, that we can give families more information about not only how their child is affected but how they might be affected in the future."

Lindsay: So, this feeling that like we’ve been on this deserted island for eight years and now all of a sudden, you’re sort of looking around through the branches of the trees. It’s like, wait a minute, there are other people on this island and in this case actually there's a lot more people on this island. Yeah, it’s very exciting, it’s validating. It gives us a lot of hope and, you know, it has been quite emotional too and also a bit of an identity shift. Being undiagnosed had become quite a big part of our identity, and so now that’s kind of shifting a little bit that we have this new diagnosis and are part of a new community. Naimah: My name is Naimah Callachand and I’m Head of Product Engagement and Growth at Genomics England. On today’s episode, I’m joined by Lindsay Pearse whose son Lars recently received a genetic diagnosis, made possible by research using data from the National Genomic Research Library, Sarah Wynn CEO of Unique, and Emma Baple, a clinical genetics doctor. Today we’ll be discussing the impact of recent research findings which have found a genetic change in the non-coding RNU4-2 gene, to be linked to neurodevelopmental conditions. If you enjoy today’s episode, we’d love your support. Please like, share and rate us on wherever you listen to your podcasts. Naimah: And first of all, I would like everyone to introduce themselves. So, Lindsay, maybe if we could come to you first. Lindsay: Great, thank you. So, thank you for having me. I’m Lindsay Pearse, I live outside of Washington DC and I’m a mum to 3 boys. My oldest son Lars who is 8, he was recently diagnosed with the de novo variant in the RNU4-2 gene. Naimah: Thank you. And Emma? Emma: My name is Emma Baple. I’m a Clinical Genetics Doctor which means I look after children and adults with genetic conditions. I’m also a Professor of Genomic Medicine in the University of Exeter and the Medical Director of the Southwest NHS Genomic Laboratory Hub. Naimah: And Sarah? Sarah: Hi, thank you for having me. I’m Sarah Wynn, I’m the CEO of a patient organisation called Unique, and we provide support and information to all those affected by rare genetic conditions. Naimah: Great, thank you. It’s so great to have you all here today. So, first of all Lindsay, I wonder if we could come to you. So, you mentioned in your introduction your son Lars has recently been diagnosed with the de novo variant. I wondered if you could tell us a bit about your story, and what it’s been like up until the diagnosis. Lindsay: Sure, yeah. So, Lars is, he’s a wonderful 8 year-old boy. With his condition, his main symptoms he experiences global developmental delays, he’s non-verbal. He’s had hypertonia pretty much since birth and wears AFO’s to support his ...
