MalaCards based summary: Albinism, Oculocutaneous, Type Ia, also known as oculocutaneous albinism type 1, is related to minimal pigment oculocutaneous albinism type 1 and acute kidney tubular necrosis, and has symptoms including photophobia, photophobia and Array. An important gene associated with Albinism, Oculocutaneous, Type Ia is TYR (Tyrosinase), and among its related pathways is Melanin biosynthesis. Affiliated tissues include skin, eye and retina, and related mouse phenotypes are hearing/vestibular/ear and pigmentation.

NIH Rare Diseases:48 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. last updated: 11/7/2011

UniProtKB/Swiss-Prot:70 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.
