obsolete skin/hair/eye pigmentation, variation in, 1

MONDO:0044255

OBSOLETE. Multiple genes influence normal human skin, hair, and/or eye pigmentation. Pigmentation phenotypes influenced by variation in the OCA2 gene are termed SHEP1. The SHEP2 association (OMIM:266300) is determined by variation at the MC1R locus (OMIM:155555) and describes a phenotype predominantly characterized by red hair and fair skin. SHEP3 (OMIM:601800) encompasses pigment variation influenced by the TYR gene (OMIM:606933); SHEP4 (OMIM:113750), that influenced by the SLC24A5 gene (OMIM:609802). Variation in the SLC45A2 (OMIM:606202) and SLC24A4 (OMIM:609840) genes result in the phenotypic associations SHEP5 (OMIM:227240) and SHEP6 (OMIM:210750), respectively. Sequence variation thought to affect expression of KITLG (OMIM:184745) results in the SHEP7 (OMIM:611664) phenotypic association. SHEP8 (OMIM:611724) is associated with variation in the IRF4 gene (OMIM:601900). Polymorphism in the 3-prime untranslated region of the ASIP gene (OMIM:600201) influences the SHEP9 association (OMIM:611742). The SHEP10 association (OMIM:612267) comprises variation in the TPCN2 gene (OMIM:612163), and SHEP11 (OMIM:612271) is associated with polymorphism near the TYRP1 gene (OMIM:115501).
