Mutations in the von Hippel-Lindau (VHL) gene are pathogenic in VHL disease, congenital polycythaemia and clear cell renal carcinoma (ccRCC). pVHL forms a ternary complex with elongin C and elongin B, critical for pVHL stability and function, which interacts with Cullin-2 and RING-box protein 1 to target hypoxia-inducible factor for polyubiquitination and proteasomal degradation. We describe a comprehensive database of missense VHL mutations linked to experimental and clinical data. We use predictions from in silico tools to link the functional effects of missense VHL mutations to phenotype. The risk of ccRCC in VHL disease is linked to the degree of destabilization resulting from missense mutations. An optimized binary classification system (symphony), which integrates predictions from five in silico methods, can predict the risk of ccRCC associated with VHL missense mutations with high sensitivity and specificity. We use symphony to generate predictions for risk of ccRCC for all possible VHL missense mutations and present these predictions, in association with clinical and experimental data, in a publically available, searchable web server.
冯·希佩尔-林道(VHL)基因的突变在VHL病、先天性红细胞增多症和透明细胞肾细胞癌(ccRCC)中具有致病性。pVHL与延伸蛋白C和延伸蛋白B形成三元复合物,这对pVHL的稳定性和功能至关重要,该复合物与Cullin-2和环盒蛋白1相互作用,以靶向缺氧诱导因子进行多聚泛素化和蛋白酶体降解。我们描述了一个与实验和临床数据相关的错义VHL突变综合数据库。我们使用计算机工具的预测结果将错义VHL突变的功能效应与表型联系起来。VHL病中ccRCC的风险与错义突变导致的不稳定程度相关。一种优化的二元分类系统(symphony)整合了五种计算机方法的预测结果,能够以高灵敏度和特异性预测与VHL错义突变相关的ccRCC风险。我们使用symphony对所有可能的VHL错义突变的ccRCC风险进行预测,并将这些预测结果与临床和实验数据一起呈现在一个公开可用、可搜索的网络服务器上。
