A Missense Mutation in OPA1 Causes Dominant Optic Atrophy in a Chinese Family.

Our results suggest that the p.D438G mutation in OPA1 causes optic atrophy in this family. The patients who carried the mutation demonstrated heterogeneous clinical manifestations in this family. This is the first report on the c.1313A>G (p.D438G) mutation of OPA1 in a Chinese family affected with DOA.
