Genome-wide association studies (GWASs) of renal cell cancer (RCC) have identified four susceptibility loci thus far. To identify an additional RCC common susceptibility locus, we conducted a GWAS and performed a meta-analysis with published GWASs (totalling 2215 cases and 8566 controls of European background) and followed up the most significant association signals [nine single nucleotide polymorphisms (SNPs) in eight genomic regions] in 3739 cases and 8786 controls. A combined analysis identified a novel susceptibility locus mapping to 2q22.3 marked by rs12105918 (P = 1.80 × 10(-8); odds ratio 1.29, 95% CI: 1.18-1.41). The signal localizes to intron 2 of the ZEB2 gene (zinc finger E box-binding homeobox 2). Our findings suggest that genetic variation in ZEB2 influences the risk of RCC. This finding provides further insights into the genetic and biological basis of inherited genetic susceptibility to RCC.
全基因组关联研究(GWAS)已经确定了迄今为止四个肾细胞癌(RCC)的易感性位点。为了鉴定一个额外的 RCC 常见易感性位点,我们进行了 GWAS,并与已发表的 GWAS 进行了荟萃分析(共包括 2215 例欧洲背景的病例和 8566 例对照),并对最显著的关联信号(八个基因组区域中的九个单核苷酸多态性 [SNPs])在 3739 例病例和 8786 例对照中进行了随访。综合分析确定了一个新的易感性位点,定位于 2q22.3,由 rs12105918 标记(P = 1.80×10(-8);优势比 1.29,95%置信区间:1.18-1.41)。该信号定位于 ZEB2 基因(锌指 E 盒结合同源盒 2)的内含子 2。我们的研究结果表明,ZEB2 中的遗传变异影响 RCC 的风险。这一发现为遗传易感性 RCC 的遗传和生物学基础提供了进一步的见解。
