Summary
In this episode, our guests explore the impact of genetic discoveries on inherited retinal dystrophies, in particular retinitis pigmentosa (RP). The discussion highlights a recent study that identified two non-coding genetic variants linked to RP, predominantly in individuals of South Asian and African ancestry. The conversation highlights how advances in whole genome sequencing are uncovering previously hidden causes of genetic disease, improving diagnostic rates, and shaping the future of patient care. It also addresses the challenges faced by individuals from diverse backgrounds in accessing genetic testing, including cultural barriers, awareness gaps, and historical underrepresentation in genomic research. Our host Naimah Callachand is joined by researcher Dr Gavin Arno, Associate Director for Research at Greenwood Genetic Centre in South Carolina, Kate Arkell, Research Development Manager at Retina UK, and Bhavini Makwana, a patient representative diagnosed with retinitis pigmentosa and Founder and Chair of BAME Vision. We also hear from Martin Hills, an individual diagnosed with autosomal dominant retinitis pigmentosa.

We understand better the progression of the disease when we can study this in many individuals from a wide spectrum of ages and different backgrounds. We can provide counselling as Bhavini was talking about. We can provide patients with a bette…
