PINES (Phenotype-Informed Noncoding Element Scoring)

Functional characterization of the noncoding genome is essential for the biological understanding of gene regulation and disease. Here, we introduce the computational framework PINES (Phenotype-Informed Noncoding Element Scoring) which evaluates the functional impact of noncoding variants in an unsupervised setting by integrating epigenetic annotations from diverse sources in a phenotype-dependent manner. A unique feature of PINES is that analyses may be customized towards genomic annotations of the highest relevance to phenotypes of interest. We show that PINES identifies functional noncoding variation more accurately than methods that do not use phenotype-weighted knowledge. To demonstrate its versatility, we show how PINES can be applied to systematically distinguish variants in enhancer regions from background variation, to delineate high-penetrance noncoding variants leading to Mendelian phenotypes, or to pinpoint epigenetic signals underlying noncoding alleles at GWAS loci. We further show how PINES can help interpret the results of fine-mapping approaches and predict novel causal alleles from GWAS on Parkinson's and inflammatory bowel disease. Its flexibility and ease of use through a dedicated web portal establish PINES as a powerful new in silico method to prioritize and assign functions to noncoding genetic variants.
