提出了一种用于从SNP阵列数据中调用拷贝数变异的高度灵敏和可配置的方法,该方法可以识别甚至罕见的CNVs拷贝数变异(CNVs)在人类疾病中具有作用,并且DNA微阵列是识别它们的重要工具。在本文中,我们框架CNV识别作为一个目标函数优化问题。我们将我们的方法应用于来自数百个样本的数据,并证明了其在不牺牲特异性的情况下以高灵敏度检测CNV的能力。它的性能与目前可用的方法相比毫不逊色,它揭示了以前未报告的收益和损失。
A highly sensitive and configurable method for calling copy number variants from SNP array data is presented that can identify even rare CNVs Copy number variants (CNVs) have roles in human disease, and DNA microarrays are important tools for identifying them. In this paper, we frame CNV identification as an objective function optimization problem. We apply our method to data from hundreds of samples, and demonstrate its ability to detect CNVs at a high level of sensitivity without sacrificing specificity. Its performance compares favorably with currently available methods and it reveals previously unreported gains and losses.
