The R402Q tyrosinase variant does not cause autosomal recessive ocular albinism
ReviewOetting WS et al.(2009)· American Journal of Medical Genetics Part A

Genome-wide association studies and comparative genomics have identified major pigmentation loci (SLC24A5, SLC45A2, TYR, OCA2, MC1R, IRF4, TPCN2) showing evidence of strong natural selection in human populations. Light skin variants in Europeans and Asians underwent complete or near-complete selective sweeps, with SLC24A5 rs1426654 and SLC45A2 variants representing independent evolutionary mechanisms. Critical skin-lightening variants arose 11,000-30,000 years ago during human demographic expansion, driven by UV radiation exposure, vitamin D synthesis requirements, and possibly sexual selection.
