A study published in Nature elucidates the genomic landscape of colorectal cancer (CRC). Researchers performed whole-genome sequencing of CRC samples from participants in the UK 100,000 Genomes Project. Analysis of the samples (n = 2,023) identified >250 putative driver genes of CRC and characterized subgroups of CRC. For example, the researchers clustered microsatellite-stable CRC into four distinct subgroups and also characterized rare CRC subgroups. In addition, they identified a potential role in CRC for the mutational signature SBS93, among others.
