ARTICLE 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% confidence interval (CI), 0.64–0.91; P = 0.0022]. The frequency of this allele was higher than that observed in the European-ancestry GWAS (0.56 and 0.07, respectively, among controls). The rs7105934 association was stronger for clear cell RCC (ccRCC: OR, 0.56; P = 7.4 × 10−7) and absent for cases of other or unknown histology (OR, 1.02; P = 0.86). Analyses of rs7105934 by subtype among European-ancestry participants from these studies yielded similar findings (ORs 0.69 and 0.92, respectively). This study provides, to our knowledge, the first evidence that rs7105934 is an RCC susceptibility locus among AAs. Our finding that the association with this SNP may be specific to clear-cell RCC is novel and requires additional investigation. Additional investigation of rs10771279 and other suggestive GWAS findings is also needed. Cancer Epidemiol Biomarkers Prev; 23(1); 209–14. ©2013 AACR.
