Mutational analysis of the OA1 gene in ocular albinism.

Abstract

Ocular albinism type 1 (OA1) is an X-linked disorder, mainly characterized by a severe reduction in visual acuity, foveal hypoplasia, nystagmus, hypopigmentation of the retina, the presence of macromelanosomes in the skin and eyes, and the misrouting of optic pathways, resulting in the loss of stereoscopic vision. We screened the OA1 gene for mutations in three unrelated Canadian and French families and in two isolated patients with OA1. We found three different missense mutations and two different nonsense mutations, three of which were novel. To date, 41 mutations (including missense mutations, insertions, and deletions) have been reported in the OA1 gene. Mutation and polymorphism data for this gene are available from the international albinism center albinism database website: http://www.cbc.umn.edu/tad/oa1map.htm.
