Heterozygous germline <i>MSH3</i> mutations, and probably <i>MLH3</i> mutations, act as classical tumour suppressors, leading to excess somatic deletion mutations, signature ID4 and increased colorectal cancer risk

Heterozygous germline mutations in MSH3 and MLH3 are associated with increased colorectal cancer risk, suggesting they may be included in genetic screening for CRC.
2.2-fold increased risk of CRC for heterozygous MSH3 mutations, P=6.6x10^-5
