  • Advances in mutant gene sequences of hereditary colorectal cancer

    ObjectiveTo summarize the progress in mutant gene sequences of different types of hereditary colorectal cancer.MethodThe relevant literatures about genetic mutations in hereditary colorectal cancer at home and abroad were reviewed.ResultsHereditary colorectal cancer coule be divided into two categories according to whether it was related to the germline mutations of known oncogenes. Among the known germline mutant genes, the gene of adenomatous polyposis coli (APC), MUTYH, thymidine glycol DNA glycosylase 1 (NTHL1), polymerase (DNA) epsilon, catalytic subunit (POLE), and polymerase (DNA) delta 1, catalytic subunit (POLD1) were closely related to adenomatous polyposis syndromes, mismatch repair (MMR)-related genes were related to Lynch syndrome, serine/threonine kinase 11 (STK-11) gene was related to Peutz-Jeghers syndrome, mutant genes of SMAD4 and bone morphogenetic protein receptor type 1A (BMPR1A) were found in JPS individuals, and Cowden syndrome was caused by phosphatase and tensin homology deleted on chromosome ten (PTEN) gene mutation. For colorectal cancer patients with unknown germline mutations but significant genetic characteristics (such as hyperplastic polyposis), relevant genes had also been gradually searched out, which needed further evidence.ConclusionsColorectal cancer is a malignant tumor with genetic characteristics. Compared with sporadic colorectal cancer, the time of hereditary colorectal cancer from adenoma to cancer is shorter, and the occurrence of heterogeneous tumor is also increased, but the survival rate after active intervention is higher than the sporadic one. To study the mutant gene sequences of hereditary colorectal cancer is the improvement and development of the diseases control in modern medicine.
