Single nucleotide polymorphisms (SNPs) included in the African American genetic risk score (GRS-A).

Note: SNPs are the set of genome-wide significant SNPs discovered in the GWAS meta-analysis by Monda and colleagues [17]. 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) YRI reference sample). Frequencies of BMI-increasing alleles are reported separately for white and black Add Health study members meeting genotype quality control criteria.
