Summaries for Albinism, Oculocutaneous, Type Ia

OMIM : 57 Oculocutaneous albinism is a genetically heterogeneous congenital disorder characterized by decreased or absent pigmentation in the hair, skin, and eyes. The term 'albinism' includes specific ocular changes that are the results of reduced amounts of melanin in the developing eye; these abnormalities in the eye and optic system are specific and necessary for the diagnosis. Aside from decreased pigment in the iris and retina, optic changes include decreased visual acuity, misrouting of the optic nerves at the chiasm, and nystagmus (King et al., 2001). Although OCA caused by mutations in the TYR gene was classically known as 'tyrosinase-negative' OCA, Tripathi et al. (1992) noted that some patients with 'tyrosinase-positive' OCA may indeed have TYR mutations resulting in residual enzyme activity. These patients can be classified as having OCA1B. (203100)

MalaCards based summary : Albinism, Oculocutaneous, Type Ia, also known as oculocutaneous albinism type 1, is related to albinism, oculocutaneous, type ib and albinism, oculocutaneous, type ii, and has symptoms including photophobia An important gene associated with Albinism, Oculocutaneous, Type Ia is TYR (Tyrosinase), and among its related pathways/superpathways is Melanin biosynthesis. The drugs Dymista and Patanase have been mentioned in the context of this disorder. Affiliated tissues include skin, eye and retina, and related phenotypes are nystagmus and visual impairment

Disease Ontology : 12 An oculocutaneous albinism that has material basis in an autosomal recessive null mutation of TYR on chromosome 11q14.3 with no residual protein activity.

NIH Rare Diseases : 53 Oculocutaneous albinism type 1 is a condition that affects the coloring of the skin, hair, and eyes. Signs and symptoms include very fair skin, white hair, an increased risk for skin damage with sun exposure, reduced vision (sharpness), light colored irises, nystagmus, and photophobia (eyes are sensitive to light). It is caused by changes in the TYR gene and is inherited in an autosomal recessive fashion.

UniProtKB/Swiss-Prot : 75 Albinism, oculocutaneous, 1A: An autosomal recessive disorder in which the biosynthesis of melanin pigment is absent in skin, hair, and eyes. It is characterized by complete lack of tyrosinase activity due to production of an inactive enzyme. Patients present with a life-long absence of melanin pigment after birth, and manifest increased sensitivity to ultraviolet radiation with predisposition to skin cancer. Visual anomalies include decreased acuity, nystagmus, strabismus and photophobia.
