[PMID 19103647] rs12934922 (R267S) and rs7501331 (A379V) double mutant have a reduced catalytic activity of beta-carotene by 57%. Female volunteers carrying the T variant of rs7501331 (379V) had a 32% lower ability to convert Beta-carotene, and those carrying at least one T in both SNPs show a 69% lower ability to convert Beta-carotene into retinyl esters.
rs7501331: the frequency of the wild-type C allele and variant T allele was 76 and 24%, respectively; 56% of the population was CC wild-type genotype, and 39% was heterozygote CT with the TT variant present in 5% of the population.
rs12934922: the frequency of the wild-type A allele and variant T allele was 58 and 42%, respectively; 38% of the population was AA wild-type genotype, 40% was heterozygote AT, and 22% was TT homozygote
