Admixture mapping and fine-mapping of birth weight loci in the Black Women’s Health Study

Several genome-wide association studies (GWAS) have identified genetic variants associated with birth weight. To date, however, most GWAS of birth weight have focused primarily on European ancestry samples even though prevalence of low birth weight is higher among African-Americans. We conducted admixture mapping using 2918 ancestral informative markers in 2596 participants of the Black Women’s Health Study, with the goal of identifying novel...
