Ocular albinism with late-onset sensorineural deafness (OASD), is a rare, X-linked inherited type of ocular albinism described in one African kindred (7 males over 3 generations) to date, characterized by severe visual impairment, translucent pale-blue iridies, a reduction in the retinal pigment and moderately severe deafness by middle age (fourth to fifth decade of life). It is unclear whether it is allelic to X-linked recessive ocular albinism or a contiguous gene syndrome.
Features include: Albinism, Nystagmus, Depigmented fundus, and Nystagmus-induced head nodding and 4 more.
