The Cancer Mutation Census (CMC) project is an undertaking to classify coding mutations in COSMIC and identify variants driving different types of cancer. The CMC integrates all coding somatic mutations collected by COSMIC with biological and biochemical information from multiple sources, combining data obtained from manual curation and computational analyses. Metrics like ClinVar significance, dN/dS ratios, and variant frequencies in normal populations (gnomAD) have been integrated into this resource. They have been used alongside COSMIC data on mutations' prevalence across 1,500 forms of human cancer. This helps to predict candidates for driver mutations in the coding portion of the genome.
