Summaries for Albinism, Oculocutaneous, Type Iii

NIH Rare Diseases : 49 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 79433Disease definitionType 3 oculocutaneous albinism (OCA3) is a form of oculocutaneous albinism (OCA; see this term) characterized by rufous or brown albinism and occurring mainly in the African population.EpidemiologyOCA3 has an estimated prevalence of 1/8,500 individuals in Africa. It is rarely seen in other populations.Clinical descriptionVisual anomalies, such as nystagmus, are frequently undetectable and patients usually present with one of two phenotypes: rufous OCA (ROCA), characterized by red-bronze skin color, blue or brown irises and ginger-red hair, or brown OCA (BOCA), characterized by light to brown hair and a light to brown or tan skin color. The clinical features of OCA3 have been considered as rather mild, and in the rare cases of non-African patients, reddish hair color has been reported. A Japanese girl was reported with having OCA3 who presented with blond hair and light skin (with a small Mongolian spot), was able to tan and was negative for nystagmus.EtiologyOCA3 is caused by a mutation in the tyrosinase-related protein 1, TYRP1, gene located on chromosome 9p23. The majority of BOCA cases are seen in OCA2, but a few BOCA phenotypes have been reported with mutations in the TYRP1 gene, indicating OCA3.Genetic counselingOCA3 is inherited autosomal recessively and genetic counseling is possible.Visit the Orphanet disease page for more resources.

MalaCards based summary : Albinism, Oculocutaneous, Type Iii, also known as oculocutaneous albinism type 3, is related to growth and developmental retardation, ocular ptosis, cardiac defect, and anal atresia and albinism, and has symptoms including nystagmus, strabismus and cutaneous photosensitivity. An important gene associated with Albinism, Oculocutaneous, Type Iii is TYRP1 (Tyrosinase Related Protein 1). Affiliated tissues include skin and eye.

UniProtKB/Swiss-Prot : 71 Albinism, oculocutaneous, 3: An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. Tyrosinase activity is normal and patients have only moderate reduction of pigment. The eyes present red reflex on transillumination of the iris, dilution of color of iris, nystagmus and strabismus. Darker-skinned individuals have bright copper-red coloration of the skin and hair.
