Genome-scale identification of microRNA-related SNPs associated with risk of head and neck squamous cell carcinoma.

ABSTRACT: Polymorphisms in microRNAs and their target sites can disrupt microRNA-dependent gene regulation, and have been associated with cancer susceptibility. However, genome-scale analyses of microRNA-related genetic variation in cancer are lacking. We tested the associations of ~40 000 common [minor allele frequency (MAF) ≥5%], microRNA-related single nucleotide polymorphisms (miR-SNPs), with risk of head and neck squamous cell carcinoma (HNSCC) in a discovery population, and validated selected loci in an independent population among a total of 2198 cases and 2180 controls. Joint analyses across the discovery and validation populations revealed six novel miR-SNP associations with risk of HNSCC. An upstream variant of MIR548H4 (rs7834169), replicated its association with overall HNSCC risk as wel
