rs10973320 and RAD51AP1. rs10973320 demonstrated genetic variability in the YRI population as well as an association between genotype and both (A) AUC (P = 2 × 10−5) and (B) expression of RAD51AP1 (P = 4 × 10−8). (A,B) This SNP is not variable in the CEU population. (C) Expression of RAD51AP1 and AUC were significantly correlated in the YRI population.
