“…Rs4889286 or rs56389940, in composite LD with rs6564851 and in the same upstream area, was selected for the b-carotene, a-carotene, and lutein/zeaxanthin gene scores. SNPs upstream of BCMO1, rs7501331 + rs12934922, and rs7501331 alone were previously reported to reduce BCMO1 activity and were associated with fasting plasma b-carotene (7,9). Here, the rs12934922 T allele was positively associated with plasma b-carotene, and either rs12934922 or rs4889293, in composite LD with rs12934922, was selected for the provitamin A carotene gene scores.…”
