N2 - In genome-wide association studies (GWAS) of common genetic variants associated with circulating alphaand gamma-tocopherol concentrations in two adult cohorts comprising 5006 men of European descent, we observed three loci associated with alpha-tocopherol levels, two novel single-nucleotide polymorphisms (SNPs), rs2108622 on 19pter-p13.11 (P = 1.7 × 10 -8) and rs11057830 on 12q24.31 (P = 2.0 × 10 -8) and confirmed a previously reported locus marked by rs964184 on 11q23.3 (P = 2.7 × 10 -10). The three SNPs have been reported to be associated with lipid metabolism and/or regulation. We replicated these findings in a combined meta-analysis with two independent samples, P = 7.8 × 10 -12 (rs964184 on 11q23.3 near BUD13, ZNF259 and APOA1/C3/A4/A5), P = 1.4 × 10 -10 (rs2108622 on 19pter-p13.11 near CYP4F2) and P = 8.2 × 10 -9 (rs11057830 on 12q24.31 near SCARB1). Combined, these SNPs explain 1.7% of the residual variance in log alpha-tocopherol levels. In one of the two male GWAS cohorts (n = 992), no SNPs were significantly associated with gamma-tocopherol concentrations after including data from the replication sample for 71 independent SNPs with P < 1 × 10 -4 identified.
