Summary

In this podcast, Dr. Ashwin Dalal, head of diagnostics at the Centre for DNA Fingerprinting and Diagnostics (CDFD) in India, discusses the landscape of rare genetic diseases in India. He explains that while over 7,000 genetic diseases are known, only about 7,000 of the ~19,500 genes have known disease associations, leaving many patients undiagnosed. He describes the National Mission Program for Pediatric Rare Genetic Disorders, a collaborative effort involving 16 institutes, which has sequenced over 2,000 families and identified several novel genes. Dr. Dalal shares his experience discovering the BHLHA9 gene, which causes limb malformations, and highlights the importance of functional validation using model organisms. He also discusses the burden of rare diseases in India, estimating around 7 crore (70 million) patients, and the government’s initiatives such as the National Rare Disease Policy 2021 and the establishment of Centers of Excellence. A notable anecdote involves a patient with ADCY5-related movement disorder whose symptoms were alleviated by caffeine, illustrating the potential of simple treatments based on genetic insights. Finally, he introduces the National Genomics Core, a facility providing affordable sequencing services to researchers and students.
