MUTYH Associated Polyposis (MAP)
MUTYH Associated Polyposis (MAP), a Polyposis predisposition caused by biallelic mutations in the Base Excision Repair (BER) gene MUTYH, confers a marked risk of colorectal cancer (CRC). The MAP phenotype is difficult to distinguish from other hereditary CRC syndromes. Especially from Familial Adenomatous Polyposis (FAP) and to a lesser extend Lynch Syndrome, which are caused by germline mutati...
متن کاملMUTYH- Associated Polyposis
Lynch syndrome and familial adenomatous polyposis (FAP) have long been identifi ed as hereditary predisposition syndromes to colorectal cancer (CRC), most easily recognized on the basis of their autosomal dominant inheritance, young age of onset of CRC and other associated malignancies, and, in the case of FAP, the presence of adenomatous polyposis. However, in 2002 the fi rst report of a novel...
متن کاملDistinct PTEN mutational spectra in hereditary non-polyposis colon cancer syndrome-related endometrial carcinomas compared to sporadic microsatellite unstable tumors.
Germline PTEN mutations cause Cowden syndrome (CS) and Bannayan-Riley-Ruvalcaba syndrome (BRR), two hamartoma-tumor syndromes with an increased risk of breast, thyroid and endometrial cancers. Somatic genetic and epigenetic inactivation of PTEN is involved in as high as 93% of sporadic endometrial carcinomas (EC), irrespective of microsatellite status, and can occur in the earliest precancers. ...
متن کاملMicrosatellite unstable gastrointestinal neuroendocrine carcinomas: a new clinicopathologic entity.
Gastroenteropancreatic (GEP) neuroendocrine carcinomas (NECs) and mixed adenoneuroendocrine carcinomas (MANECs) are heterogeneous neoplasms characterized by poor outcome. Microsatellite instability (MSI) has recently been found in colorectal NECs showing a better prognosis than expected. However, the frequency of MSI in a large series of GEP-NEC/MANECs is still unknown. In this work, we investi...
متن کاملHereditary Colorectal Tumors: A Literature Review on MUTYH-Associated Polyposis
MAP (MUTYH-associated polyposis) is a syndrome, described in 2002, which is associated with colorectal adenomas, with enhanced colorectal carcinogenesis. This review synthesizes the available literature on MAP and outlines its pathogenesis, association with colorectal tumorigenesis, screening, treatment, and the subtle differences between it and its close cousins-FAP and AFAP. The preponderance...
