Mismatch repair cancer syndrome (MMRCS) is a cancer syndrome associated with biallelic DNA mismatch repair mutations.[1] It is also known as Turcot syndrome (after Jacques Turcot, who described the condition in 1959) and by several other names.[1]
In MMRCS, neoplasia typically occurs in both the gut and the central nervous system (CNS).[1] In the large intestine, familial adenomatous polyposis occurs; in the CNS, brain tumors.
Genetics
Under the name constitutional mismatch repair-deficiency, (CMMR-D), it has been mapped to MLH1, MSH2, MSH6 or PMS2.[2] Although these are the same genes mutated in the condition known as Lynch syndrome or hereditary nonpolyposis colorectal cancer, the mutations are biallelic in CMMR-D.[3]
The term "childhood cancer syndrome" has also been proposed.[4][5]
Café-au-lait macules have been observed.[6]
Synonyms
- Brain tumor-polyposis syndrome
- Glioma-polyposis syndrome
- OMIM currently includes "Turcot syndrome" under Mismatch repair cancer syndrome. Turcot syndrome is the association between familial polyposis of the colon and brain tumors[7] like medulloblastoma, malignant glioma. It was first reported by Canadian surgeon Jacques Turcot (1914- ) et al. in 1959 and hence carries the first author's name.[8]
