We conducted a two-stage genome-wide association study of renal cell carcinoma (RCC) in 3,772 affected individuals (cases) and 8,505 controls of European background from 11 studies and followed up 6 SNPs in 3 replication studies of 2,198 cases and 4,918 controls. Two loci on the regions of 2p21 and 11q13.3 were associated with RCC susceptibility below genome-wide significance. Two correlated variants (r² = 0.99 in controls), rs11894252 (P = 1.8 × 10⁻⁸) and rs7579899 (P = 2.3 × 10⁻⁹), map to EPAS1 on 2p21, which encodes hypoxia-inducible-factor-2 alpha, a transcription factor previously implicated in RCC. The second locus, rs7105934, at 11q13.3, contains no characterized genes (P = 7.8 × 10⁻¹⁴). In addition, we observed a promising association on 12q24.31 for rs4765623, which maps to SCARB1, the scavenger receptor class B, member 1 gene (P = 2.6 × 10⁻⁸). Our study reports previously unidentified genomic regions associated with RCC risk that may lead to new etiological insights.
我们进行了两阶段的全基因组关联研究肾细胞癌(RCC)在 3772 名受影响的个体(病例)和 11 项研究中的 8505 名欧洲背景对照者中,并对 6 个 SNP 进行了 3 个复制研究,共 2198 例病例和 4918 例对照。在全基因组范围内,两个位于 2p21 和 11q13.3 区域的位点与 RCC 易感性相关,但未达到显著水平。两个相关的变异体(在对照中 r²=0.99),rs11894252(P=1.8×10⁻⁸)和 rs7579899(P=2.3×10⁻⁹),映射到 2p21 上的 EPAS1,该基因编码缺氧诱导因子-2α,一种先前被认为与 RCC 有关的转录因子。第二个位于 11q13.3 的位点 rs7105934 不包含已鉴定的基因(P=7.8×10⁻¹⁴)。此外,我们在 12q24.31 上观察到 rs4765623 的一个很有前途的关联,该基因位于 SCARB1,即清道夫受体 B 型,成员 1 基因(P=2.6×10⁻⁸)。我们的研究报告了以前与 RCC 风险相关的未被识别的基因组区域,这可能导致新的病因学见解。
