Evolutionary Origin of Ocular Melanoma: Associations With rs12913832 G Allele Frequency and Latitude. [PDF]

Cancer Med
The rs12913832 derived (G) allele frequency (blue‐eye allele) was a markedly stronger predictor of ocular melanoma incidence than geographic latitude, with approximately 92% of the latitude effect mediated through allele frequency. These findings indicate that pigmentation‐related genetic variation contributes substantially to global differences in ...
