Identifying pathways modulating sleep duration: from genomics to transcriptomics
Abstract Recognizing that insights into the modulation of sleep duration can emerge by exploring the functional relationships among genes, we used this strategy to explore the genome-wide association results for this trait. We detected two major signalling pathways (ion channels and the ERBB signall...
