Genetic variants

The Ala-111 allele predominates (93 to 100%) in African and East Asian populations. In contrast, the Thr-111 allele is nearly fixed (98.7 to 100%) in European populations, is associated with a substantial reduction in regional heterozygosity, and correlates with lighter skin pigmentation in admixed populations.
