For haplotype designation, 1 or 2 refers to the major or minor alleles, respectively, in the following order: rs7578326, rs2943634, rs2943641, and rs2713538; data are means (95% CI) in arbitrary units (AU) of 92 subjects, adjusted for age, sex, and BMI; global haplotype effect for LOC646736 and ; n.s., not significant. Transcript quantification of LOC646736 (with primers targeting exons 6 and 7) and IRS1 are normalized for RPL0.
