Lynch Syndrome (Hereditary Nonpolyposis Colorectal Cancer)
2019年10月23日 · Lynch syndrome results from a germline mutation in 1 of 4 mismatch repair (MMR) genes: MLH1, MSH2, MSH6, and PMS2. Large deletions in a non-mismatch repair gene called epithelial cellular adhesion molecule ( EPCAM ), which silences MSH2 expression, have also been found to cause Lynch syndrome.

2004年2月5日 · Lynch syndrome is caused by pathogenic variants in genes involved with the mismatch repair (MMR) pathway. This pathway functions to identify and remove single-nucleotide mismatches or insertions and deletion loops. Pathogenic variants in four of the MMR genes can cause Lynch syndrome [Peltomäki 2003].
Lynch Syndrome: Signs/Symptoms, Causes, Outlook - Cleveland Clinic
What causes Lynch syndrome? A genetic mutation (genetic change) in one of five genes that are responsible for fixing errors in DNA (mismatch repair gene) causes Lynch syndrome. The five genes are: MLHL. MSH2. MSH6. PMS2. EPCAM.
Lynch syndrome - Symptoms and causes - Mayo Clinic
2024年3月8日 · People with Lynch syndrome have mismatch repair genes that don't work as expected. If an error happens in the DNA, it might not get fixed. This could cause cells that grow out of control and become cancer cells. Lynch syndrome runs in families in an autosomal dominant inheritance pattern.
Lynch Syndrome - American Cancer Society
What causes Lynch syndrome? Lynch syndrome is caused by an inherited mutation in any of several genes, including: MLH1; MSH2; MSH6; PMS2; EPCAM ; These are known as mismatch repair (MMR) genes (except for EPCAM, which affects the function of the MSH2 MMR gene). The proteins encoded by MMR genes help repair damaged DNA when cells replicate ...
Lynch syndrome: MedlinePlus Genetics
Lynch syndrome, often called hereditary nonpolyposis colorectal cancer (HNPCC), is an inherited disorder that increases the risk of many types of cancer, particularly cancers of the colon (large intestine) and rectum, which are collectively referred to as colorectal cancer. Explore symptoms, inheritance, genetics of this condition.
About Lynch Syndrome | Hereditary Colorectal (Colon) Cancer
2024年10月16日 · Lynch syndrome is due to inherited changes (mutations) in the genes that normally fix mistakes made when DNA is copied. These genes (MLH1, MSH2, MSH6, PMS2, and EPCAM) normally protect you from getting certain cancers, but some mutations in these genes prevent them from working properly.
Lynch syndrome: 10 things to know about this genetic condition
2024年4月24日 · Lynch syndrome is caused by a mutation in one of the following genes: These genes are responsible for repairing mistakes in the DNA. So, if one of them stops working properly, a person becomes much more susceptible to developing cancer, particularly at a …
The genetic basis of Lynch syndrome and its implications for …
MLH1, MSH2, MSH6, and PMS2 are among the genes that produce MMR proteins. Lynch syndrome is caused by a heritable mutation in one copy of an MMR gene. At a phenotypic level, Lynch syndrome is dominant with variable expressivity.
Lynch syndrome > Fact Sheets - Yale Medicine
Not everyone with Lynch syndrome will inevitably develop cancer. Your risk depends, in part, on which of the five Lynch syndrome-responsible genes has the inherited genetic defect and the types of cancer that have been diagnosed throughout your family’s medical history.
