[PMID 23128285] Levels of 25-hydroxyvitamin D in familial longevity: the Leiden Longevity Study. Concluded that familial longevity was associated with a lower vitamin D levels and a lower frequency of the allelic variation in the CYP2R1 gene.
[PMID 20418485] Genome-wide association study of circulating vitamin D levels. This SNP is part of CYP2R1, which encodes a key C-25 hydroxylase that converts vitamin D3 to an active vitamin D receptor ligand. This SNP, along with rs2282679, rs3829251, and rs6599638 accounted for 2.8% of the variance in circulating vitamin D levels.
