Wilson's disease
Wilson's disease is a disorder characterized by the excess build-up of copper in the body. Symptoms are typically related to the brain and liver. Liver-related symptoms include vomiting, weakness, fluid build-up in the , swelling of the legs, yellowish skin, and itchiness. Brain-related symptoms include tremors, muscle stiffness, trouble in speaking, personality changes, anxiety, and psychosis.

Across the other high- (india) gene set (ATP7B), 75 -'' are actually seen in South Asians () - many European-absent and still clinically 'uncertain'. For wilson's disease, that's a pool of computationally-damaging, India-relevant, clinically-unresolved variants no one has systematically characterised.
A study that would help: Take the South-Asian-observed, European-absent, ClinVar-uncertain in ATP7B and triage them for wilson's disease: functional assays or family segregation to move them from 'uncertain' to a real call. Each reclassified is a usable diagnostic result.
A fully treatable disease that Europe's standard genetic test quietly misses in Indians
Wilson's disease — copper poisoning caused by ATP7B — is treatable if caught early and fatal if missed. But India has no single common : the European flagship H1069Q, which anchors Western testing, is essentially absent here. Indian ATP7B mutations are region- and population-specific — one South Indian study alone found 36 different mutations, 13 of them never described before.
Consanguineous and intra-caste marriage drives the up: parental runs around 38% in Wilson's patients versus ~4% in controls, with homozygosity reaching 60%. About 94% of Indian patients present before age 30. It is likely more common, and more underdiagnosed, than the records suggest.
The biology is solved and the treatment (copper chelation) works. The gap is : a Western H1069Q-first test underperforms in India, and the region-specific Indian has not been consolidated into a single validated panel. Our scan finds 75 observed South-Asian in ATP7B — the most of any gene in the set.
Assemble the region-specific Indian ATP7B into a validated India-first Wilson's panel, so a young person with unexplained liver or signs gets a answer — and treatment — before the damage becomes permanent.
