In This Issue Genetics In Medicine

Lynch syndrome or hereditary nonpolyposis colorectal cancer is an autosomal dominant genetic syndrome that predisposes individuals to multiple cancer types.

Lynch syndrome breast cancer. Win AK Jenkins MA Dowty JG et al. It is estimated that one of 279 individuals in the general population carries a pathogenic MMR gene variant 4. Mutation carriers have a substantial burden of increased risks of cancers of the colon rectum endometrium and several other organs which generally occur at younger ages than for the general population.

The known cancers associated with Lynch syndrome include colorectal and endometrial cancers as well as cancers of the stomach ovary urinary tract hepatobiliary tract pancreas small bowel and brain. By way of. The condition was formerly known as hereditary nonpolyposis colorectal cancer HNPCC before its relationship to other types of cancers was better determined.

This condition increases ones chances of getting cancer especially colon cancer and several others like endometrial cancer ovarian cancer etc. In this article we have reviewed the existing studies that investigated whether breast cancer is caused by a mutation in an MMR gene or whether the risk of breast cancer is increased for women who carry a mutation in an MMR gene. The classic tumor spectrum for Lynch Syndrome LS includes colon endometrial ovarian stomach small intestine hepatobiliary urinary tract and braincentral nervous system cancers.

This condition was previously known as hereditary non-polyposis colorectal cancer. Lynch syndrome LS also known as Hereditary Non-Polyposis Colorectal Cancer HNPCC is one of the most common hereditary cancer predisposition syndromes and is associated with increased lifetime development risk of colorectal CRC and endometrial cancer EC as well as multiple other cancer types. Lynch syndrome is an autosomal dominantly inherited disorder of cancer susceptibility caused by germline mutations in the DNA mismatch repair MMR genes.

Lynch syndrome LS is an autosomal dominantly inherited disorder which is caused by pathogenic germline variants in one of the DNA mismatch repair MMR genes MLH1 MSH2 MSH6 PMS2 or in the EPCAM gene 1 2 3. Lynch syndrome is one of the here ditary cancer predisposition sy ndromes associated with an increased lifelong risk of several types of cancer development such as colorectal en dometrial ovar. JCO Precis Oncol doi101200PO1900271 Google Scholar.

Lynch syndrome is a hereditary disorder of cancer which is of autosomal dominance. Lynch syndrome is an inherited genetic disorder associated with a predisposition to early-onset colorectal and endometrial cancers but breast cancer risk in these patients is debated. Initially raised by Henry Lynch and colleagues several decades ago the issue of breast cancer risk in Lynch syndrome has been debated with studies providing evidence for and against breast cancer being part of Lynch syndrome 4244.

Researchers have suspected that the genetic mutations linked to Lynch syndrome also were linked to breast cancer but previous research results have been mixed. People with Lynch syndrome are more likely to get colorectal cancer and other cancers and at a younger age before 50 including. Stoll J Rosenthal E Cummings S et al.

Although Lynch syndrome is the most common hereditary cancer syndrome it is probably less well known compared with other syndromes such as hereditary breast-ovarian cancer syndrome related to BRCA gene mutation and von HippelLindau syndrome which affect one in 500 to one in 1000 persons and one in 36 000 persons respectively. Researchers have been unsure if genes that cause Lynch. Of the 21 risk studies identified 13 did not observe statistical evidence for an association of breast cancer risk with Lynch syndrome while 8 studies found an increased risk of breast cancer.

In this study the researchers analyzed a database of information from more than 50000 women who had had multi-gene genetic testing for hereditary cancer between 2013 and 2015. Lynch syndrome is a genetic disorder that raises the risk of developing several types of cancer particularly colon cancer. Lynch syndrome is the most common inherited form of colorectal cancer accounting for roughly 3 percent of newly diagnosed cases.

There is also an increased risk of developing other types of cancers such as endometrial uterine stomach breast ovarian small bowel intestinal pancreatic prostate urinary tract liver kidney and bile duct cancers. People who have Lynch syndrome have a significantly increased risk of developing colorectal cancer. Lynch syndrome also known as hereditary non-polyposis colorectal cancer HNPCC is the most common cause of hereditary colorectal colon cancer.

The aim of this study is to evaluate breast cancer rates in a cohort of Lynch syndrome patients as well as to identify women who may be eligible for additional breast cancer specific genetic testing. No evidence of increased risk of breast cancer in women with Lynch syndrome identified by multigene panel testing. Prevalence and penetrance of major genes and polygenes for colorectal cancer.

Lynch syndrome is a type of genetic condition that increases a persons likelihood of developing cancers along the digestive or gynecological tract as well as other areas of the body. One in 440 Americans carries a gene variant that causes Lynch syndrome.
