Examination of allele-specific expression identifies 71 genes with excess somatic cis-regulatory effects in colorectal cancer (CRC), and 1,693 and 948 expression quantitative trait loci (eQTLs) in normal samples and tumours, respectively (with 36% of tumour eQTLs exclusive to CRC); tumour-specific eQTLs are more enriched for low CRC genome-wide association study P values and accumulate more somatic mutations than shared eQTLs, suggesting a role as germline-derived cancer regulatory drivers.
