Single nucleotide polymorphisms (SNPs) significantly associated with serum 25(OH)D levels.
Table 3.
Linear regression-derived associations between rs2298849, rs2282679, and rs10877012 and serum levels of 25(OH)D among African Americans.
Figure 1.
Genotype score in relation to serum 25(OH)D levels among African Americans.
Plot of the estimated, average decrease in serum level of 25(OH)D (y-axis) in relation to genotype score (x-axis). Genotype score equals the sum of the number of risk alleles (i.e., A for rs2298849, G for rs2282679, and G for rs10877012). Estimates were derived from a linear regression model restricted to African Americans, using a genotype score of 1 as a referent, and including covariates for sex and level of African ancestry.
