Li–Fraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder [1] that predisposes carriers to cancer development.It was named after two American physicians, Frederick Pei Li and Joseph F. Fraumeni Jr., who first recognized the syndrome after reviewing the medical records and death certificates of childhood rhabdomyosarcoma patients. [2]
Familial adenomatous polyposis is a cancer syndrome in which there are hundreds to thousands of benign adenomas in the colon.. A hereditary cancer syndrome (familial/family cancer syndrome, inherited cancer syndrome, cancer predisposition syndrome, cancer syndrome, etc.) is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the ...
Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary predisposition to colon cancer.. HNPCC includes (and was once synonymous with) [1] Lynch syndrome, an autosomal dominant genetic condition that is associated with a high risk of colon cancer, endometrial cancer (second most common), ovary, stomach, small intestine, hepatobiliary tract, upper urinary tract, brain, and skin.

Under the name constitutional mismatch repair-deficiency (CMMR-D), it has been mapped to MLH1, MSH2, MSH6 or PMS2. [2] Monoallelic mutations of these genes are observed in the condition known as Lynch syndrome or hereditary nonpolyposis colorectal cancer, while biallelic mutations are observed in CMMR-D. [3] People expressing the HNPCC (which itself is considered autosomal dominant) trait are ...
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
MLH1, MSH2, MSH6, PMS2: mutations in genes that lead to Lynch Syndrome put individuals at risk for ovarian cancer. [7] TP53: Mutations cause Li-Fraumeni syndrome. It produces particularly high rates of breast cancer among younger women with mutated genes, and despite being rare, 4% of women with breast cancer under age 30 have a mutation in ...
Dementia impacts millions of older adults, but researchers are still learning how, exactly, to prevent this devastating illness. Now, research suggests that increasing your intake of one specific ...
Breast cancer in the Cowden syndrome is associated with PTEN gene mutations, in the Li-Fraumeni syndrome with tumor protein P53 gene mutations, [34] and in the Lynch syndrome with mutations in any of the four DNA mismatch repair genes (MLH1, MSH2, MSH6, PMS2), or the EpCAM gene. [35]
