TY - JOUR T1 - Fast, scalable prediction of deleterious noncoding variants from functional and population genomic data JF - bioRxiv DO - 10.1101/069682 SP - 069682 AU - Yi-Fei Huang AU - Brad Gulko AU - Adam Siepel Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/08/15/069682.abstract N2 - Across many species, a large fraction of genetic variants that influence phenotypes of interest is located outside of protein-coding genes, yet existing methods for identifying such variants have poor predictive power. Here, we introduce a new computational method, called LINSIGHT, that substantially improves the prediction of noncoding nucleotide sites at which mutations are likely to have deleterious fitness consequences, and which therefore are likely to be phenotypically important. LINSIGHT combines a simple neural network for functional genomic data with a probabilistic model of molecular evolution. The method is fast and highly scalable, enabling it to exploit the “Big Data” available in modern genomics. We show that LINSIGHT outperforms the best available methods in identifying human noncoding variants associated with inherited diseases. In addition, we apply LINSIGHT to an atlas of human enhancers and show that the fitness consequences at enhancers depend on cell-type, tissue specificity, and constraints at associated promoters. ER -
