Summaries for Albinism, Ocular, Type I

OMIM : 57 Ocular albinism type I (OA1) is the most common form of ocular albinism. Clinical presentation of OA1 in Caucasians is characterized by nystagmus, impaired visual acuity, iris hypopigmentation with translucency, albinotic fundus, macular hypoplasia, and normally pigmented skin and hair. Carrier females usually have punctate iris translucency and a mottled pattern of fundus pigmentation. In contrast to Caucasian patients, black or Japanese patients with OA1 often have brown irides with little or no translucency and varying degrees of fundus hypopigmentation, the so-called 'nonalbinotic fundus' (summary by Xiao and Zhang, 2009). (300500)

MalaCards based summary : Albinism, Ocular, Type I, also known as ocular albinism, type i, is related to ocular albinism, x-linked and orotic aciduria. An important gene associated with Albinism, Ocular, Type I is GPR143 (G Protein-Coupled Receptor 143). The drugs Naproxen and Pharmaceutical Solutions have been mentioned in the context of this disorder. Affiliated tissues include skin, eye and bone, and related phenotypes are nystagmus and visual impairment

UniProtKB/Swiss-Prot : 75 Albinism ocular 1: Form of albinism affecting only the eye. Pigment of the hair and skin is normal or only slightly diluted. Eyes may be severely affected with photophobia and reduced visual acuity. Nystagmus or strabismus are often associated. The irides and fundus are depigmented.
