Summary

Hereditary nonpolyposis colorectal cancer type 5 is a cancer predisposition syndrome characterized by onset of colorectal cancer and/or extracolonic cancers, particularly endometrial cancer, usually in mid-adulthood. The disorder shows autosomal dominant inheritance with incomplete penetrance (summary by Castellsague et al., 2015). For a phenotypic description and a discussion of genetic heterogeneity of hereditary nonpolyposis colorectal cancer (HNPCC), see HNPCC1 (120435). [from OMIM]
