We have investigated the presence of a point mutation at position 11778 in the ND4 gene of mitochondrial DNA in 17 Japanese families with Leber's hereditary optic neuropathy (LHON), and have identified the mutation in 14 (82.4%) of the 17 families. The prevalence of this mutation appears to be much higher in Japanese patients with LHON than in patients of other ethnic origins, such as Finnish, Dutch, German, and English families.
