A review on the molecular diagnostics of Lynch syndrome: a central role for the pathology laboratory
Lynch syndrome (LS) is caused by mutations in mismatch repair genes and is characterized by a high cumulative risk for the development of mainly colorectal carcinoma and endometrial carcinoma. Early detection of LS is important since surveillance can reduce morbidity and mortality. However, the diagnosis of LS is complicated by the absence of a pre-morbid phenotype and germline mutation analysi...
متن کاملNovel Implications in Molecular Diagnosis of Lynch Syndrome
About 10% of total colorectal cancers are associated with known Mendelian inheritance, as Familial Adenomatous Polyposis (FAP) and Lynch syndrome (LS). In these cancer types the clinical manifestations of disease are due to mutations in high-risk alleles, with a penetrance at least of 70%. The LS is associated with germline mutations in the DNA mismatch repair (MMR) genes. However, the mutation...
متن کاملSome aspects of molecular diagnostics in Lynch syndrome
This manuscript is composed of five parts which summarize five publications in succession. Essentially, they are concerned with molecular diagnostics of Lynch syndrome and are based on studies in 238 families. The finding that young age at diagnosis is the key feature in patients with MSH2 and MLH1 mutations (Part 1) has helped to define simple criteria for the preliminary diagnosis of this syn...
متن کاملDiagnosing Lynch syndrome
R isk stratification is essential for designing efficacious and cost effective colon cancer screening programmes. One of the most important risk factors for colorectal cancers (CRC) is an inherited predisposition, implicated in 20% of all cases. The spectrum of genetic susceptibility ranges from the low penetrance mutations that modestly increase the colon cancer risk (for example, I 1307K) to ...
متن کاملLynch syndrome (HNPCC)
Lynch syndrome, also referred to as hereditary non-polyposis colorectal cancer (HNPCC), accounts for somewhere between 2 and 5% of all CRC. It has been shown that Lynch syndrome (LS) is a result of germline mutations in genes involved in DNA mismatch repair (MMR) MSH2, MLH1, MSH6, and PMS2, whereas as HNPCC refers to families that adhere to the Amsterdam criteria or iterations of it. More recen...
