Single-nucleotide polymorphisms included in the genetic risk score for Europeans (GRS-E).

Note: SNPs are the set of genome-wide significant SNPs discovered in the GWAS meta-analysis by the GIANT Consortium [7]. Weights are the effect-sizes estimated in that analysis. In cases where the original GWAS SNP was not available in the Add Health genotype database, linkage proxies were identified using the Broad Institute’s SNAP tool [35] (1000 Genomes (Pilot 1) CEU reference sample). No proxy was available for rs11847697 near PRKD1. Alleles are reported according to dbSNP. Frequencies of BMI-increasing alleles are reported separately for white and black Add Health study members meeting genotype quality control criteria.
