Distinguishing the driver mutations from somatic mutations in a tumor genome is one of the major challenges of cancer research. This challenge is more acute and far from solved for non-coding mutations. Here we present OncodriveFML, a method designed to analyze the pattern of somatic mutations across tumors in both coding and non-coding genomic regions to identify signals of positive selection, and therefore, their involvement in tumorigenesis. We describe the method and illustrate its usefulness to identify protein-coding genes, promoters, untranslated regions, intronic splice regions, and lncRNAs-containing driver mutations in several malignancies.
区分肿瘤基因组中的驱动突变和体细胞突变是癌症研究的主要挑战之一。对于非编码突变而言,这一挑战更为严峻且远未得到解决。在此,我们介绍OncodriveFML,这是一种旨在分析编码和非编码基因组区域中肿瘤体细胞突变模式以识别正选择信号,进而确定其在肿瘤发生中作用的方法。我们描述了该方法,并举例说明了它在识别多种恶性肿瘤中含驱动突变的蛋白质编码基因、启动子、非翻译区、内含子剪接区域和长链非编码RNA方面的实用性。
