About This Section

Entrez Gene summary for OCA2 Gene:
This gene encodes the human homologue of the mouse p (pink-eyed dilution) gene. The encoded protein is believed to
be an integral membrane protein involved in small molecule transport, specifically tyrosine - a precursor of
melanin. Mutations in this gene result in type 2 oculocutaneous albinism. (provided by RefSeq, Jul 2008)

GeneCards Summary for OCA2 Gene: 
OCA2 (oculocutaneous albinism II) is a protein-coding gene. Diseases associated with OCA2 include oculocutaneous albinism, and oculocutaneous albinism type 2. GO annotations related to this gene include transporter activity and L-tyrosine transmembrane transporter activity.

UniProtKB/Swiss-Prot: P_HUMAN, Q04671
Function: Could be involved in the transport of tyrosine, the precursor to melanin synthesis, within the
melanocyte. Regulates the pH of melanosome and the melanosome maturation. One of the components of the mammalian
pigmentary system. Seems to regulate the post-translational processing of tyrosinase, which catalyzes the
limiting reaction in melanin synthesis. May serve as a key control point at which ethnic skin color variation is
determined. Major determinant of brown and/or blue eye color

         UniProtKB/Swiss-Prot Summary: P_HUMAN, Q04671

    limiting reaction in melanin synthesis. May serve as a key control point at which ethnic skin color variation is
    determined. Major determinant of brown and/or blue eye color
    Induction: Expression is under the control of an enhancer element that is encoded in an intron of the close-by
    HERC2 gene. The enhancer element containing the T-allele of the polymorphism rs12913832 mediates binding of the
    transcription factors HLTF, LEF1 and MITF and increases OCA2 expression. In contrast, transcription factor
    binding and OCA2 expression are reduced in carriers of the C-allele of polymorphism rs12913832. Thus, people
    homozygous for the C-allele have light-colored eyes, while people homozygous for the T-allele of polymorphism
    rs12913832 most often have brown eyes

    Polymorphism: Genetic variants in OCA2 define the skin/hair/eye pigmentation variation locus 1 (SHEP1)
    [MIM:227220]; also known as skin/hair/eye pigmentation type 1, blue/nonblue eyes or skin/hair/eye pigmentation
    type 1, blue/brown eyes or skin/hair/eye pigmentation type 1, blond/brown hair or eye color, brown/blue or eye
    color, blue/nonblue or eye color type 3 (EYCL3) or brown eye color type 2 (BEY2) or hair color type 3 (HCL3).
    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. In the case of skin, individuals tend to
    have lighter pigmentation with increasing distance from the equator. By contrast, the majority of variation in
    human eye and hair color is found among individuals of European ancestry, with most other human populations fixed
    for brown eyes and black hair. OCA2 polymorphisms may act as a penetrance modifier of the risk of malignant
    melanoma

  • Albinism, oculocutaneous, 2 (OCA2) [MIM:203200]: An autosomal recessive disorder in which the
    biosynthesis of melanin pigment is reduced in skin, hair, and eyes. Although affected infants may appear at birth
    to have complete absence of melanin pigment, most patients acquire small amounts of pigment with age. Visual
    anomalies include decreased acuity and nystagmus. The phenotype is highly variable. The hair of affected
    individuals may turn darker with age, and pigmented nevi or freckles may be seen. African and African American
    individuals may have yellow hair and blue-gray or hazel irides. One phenotypic variant, 'brown OCA,' has been
    described in African and African American populations and is characterized by light brown hair and skin color and
    gray to tan irides. Note=The disease is caused by mutations affecting the gene represented in this entry
