Scanning the ocular albinism 1 (OA1) gene for polymorphisms in congenital nystagmus by DHPLC.

Background: Nystagmus is common to all types of albinism. Some subjects with nystagmus lack convincing signs of albinism, have no other visual pathway disease, and are classified as possessing congenital idiopathic nystagmus (CN). It has been postulated that CN may be a form of ocular albinism.
