Summaries for TYRP1 Gene

Entrez Gene Summary for TYRP1 Gene

  • This gene encodes a melanosomal enzyme that belongs to the tyrosinase family and plays an important role in the melanin biosynthetic pathway. Defects in this gene are the cause of rufous oculocutaneous albinism and oculocutaneous albinism type III. [provided by RefSeq, Mar 2009]

GeneCards Summary for TYRP1 Gene

TYRP1 (Tyrosinase-Related Protein 1) is a Protein Coding gene. Diseases associated with TYRP1 include albinism, oculocutaneous, type iii and sympathetic ophthalmia. Among its related pathways are Metabolism and Direct p53 effectors. GO annotations related to this gene include protein homodimerization activity and copper ion binding. An important paralog of this gene is DCT.

Polymorphic Variants from UniProtKB/Swiss-Prot for TYRP1 Gene

Genetic variants in TYRP1 define the skin/hair/eye pigmentation variation locus 11 (SHEP11) [MIM:612271] and are responsible for variability in hair color linked to chromosome 9p23 in Melanesians. Hair, eye and skin pigmentation are among the most visible examples of human phenotypic variation, with a broad normal range that is subject to substantial geographic stratification

  • Albinism, oculocutaneous, 3 (OCA3) [MIM:203290]: 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. {ECO:0000269 PubMed:16704458, ECO:0000269 PubMed:23504663}. Note=The disease is caused by mutations affecting the gene represented in this entry.
