CD160 and nonpapillary renal cell carcinoma: Interestingly, when considering the associations of HVEM and CD160 SNPs with ccRCC risk in relation to gender, we noticed that the presence of a minor allele not only in the previously mentioned SNPs (rs2234167 (HVEM) and rs2231375 (CD160)) but also in two others (rs1886730 and rs8725, located within HVEM) was significantly associated with ccRCC risk in women.
