Mutation analysis ofBEST1in Japanese patients with Best's vitelliform macular dystrophy

Twelve different variants, two of which (p.S7N and p.P346H) were novel, were identified in the 13 Japanese families with BVMD. Compound heterozygous variants were found in one proband exhibiting a typical BVMD phenotype. Our results suggest that BEST1 variants do play a large role in Japanese patients with BVMD.
