Project details

Previous studies have identified microRNA-related single nucleotide polymirphisms (miR-SNPs) associated with head and neck squamous cell carcinoma (HNSCC), in addition to other cancers. These studies are typically candidate-based and are therefore lacking in scale. We adopted a genome-wide approach to identify miR-SNPs associated with overall survival in HNSCC, using a discovery and validation phase approach. We then utilized publicaly available miRNA and mRNA expression data to provide additional support for the observed associations.

Genotyping data details

Genotype data for discovery and validation populations are being submitted to dbGAP. Accession codes linking to these data on dbGAP will be posted here once submission is complete.

R-scripts included in this repository

This repository includes R-scripts used to perform the analyses of predicted miRNA-target sites overlapping HNSCC-associated miR-SNPs, TCGA-miRseq data, and TCGA-RNAseq data.
