We then tested whether the enriched gene sets were associated with the known liver cancer gene set (http://zldev.ccbr.utoronto.ca/~ddong/diseaseHub/index.html), which integrates data from multiple sources including OMIM (Online Mendelian Inheritance in Man), GAD (Genetic Association Database), HGMD (Human Gene Mutation Database), PharmGKB (Pharmacogenomics Knowledge Base), CGP (Cancer Genome Project) and GWAS (Genome Wide Association Studies). The gene discussed is GAD1; the disease is cancer.
