Mismatch repair cancer syndrome
MONDO:0031219A rare childhood cancer predisposition syndrome caused by biallelic inheritance of mutations in MLH1, MSH2, MSH6, or PMS2 genes. It is characterized by the development of childhood cancers, usually hematological malignancies and/or brain tumors, and colorectal cancers with multiple intestinal polyps. The majority of patients show signs of neurofibromatosis type 1.
Also known as: constitutional mismatch repair deficiency syndrome
