A genome-wide association study of renal cell carcinoma among African Americans.

ABSTRACT: Genome-wide association studies (GWAS) of renal cell carcinoma (RCC) in populations of European ancestry have identified four susceptibility loci. No GWAS has been conducted among African Americans (AA), who experience a higher incidence of RCC. We conducted a GWAS in which we analyzed 1,136,723 common single-nucleotide polymorphisms (SNP) among 255 cases and 375 controls of African ancestry, and further investigated 16 SNPs in a replication set (140 cases and 543 controls). The 12p11.23 variant rs10771279, located 77 kb from the European-ancestry RCC marker rs718314, was associated with RCC risk in the GWAS (P = 1.2 × 10(-7)) but did not replicate (P = 0.99). Consistent with European-ancestry findings, the A allele of rs7105934 on 11q13.3 was associated with decreased risk [OR, 0.76, 95%
