aka c.2333G>T, p.Arg778Leu, R778L This mutation is commonly considered the most frequent ATP7B gene mutation associated with Wilson's disease in Asian populations.

C;T

Unaffected in absence of a second ATP7B gene mutation; see links via main rs-page

A;C

Unaffected in absence of a second pathogenic mutation; see Wilson's disease and ATP7B
