Single locus allelic and genotypic tests of association in Africans (2a), African-Americans (2b), and Caucasians (2b).

*In bold are statistically significant (p≤0.05).ars10631390 is a microsatellite and was coded so that alleles 131 and 134 were grouped into one category coded B here and the other alleles 125 and 128 were grouped into another category coded A. rs17860508 is an insertion deletion and the deletion (D) was considered the minor allele.bGenotype p-values for African-American and Caucasian samples are additive genotype models performed using GEE.
