What is the prognosis of familial adenomatous polyposis?
What is the prognosis of familial adenomatous polyposis?
Patients with untreated FAP have a median life expectancy of 42 years. Life expectancy is extended greatly in those treated with colectomy. Upper gastrointestinal cancers and desmoid tumors are the most common causes of death in patients who have undergone colectomy.
How is familial adenomatous polyposis passed down?
When familial adenomatous polyposis results from mutations in the APC gene, it is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with the condition.
What does familial mean in medical terms?
Familial: A condition that tends to occur more often in family members than is expected by chance alone. A familial disease may be genetic (such as cystic fibrosis) or environmental (such as chicken pox).
Is FAP fatal?
It is a very benign version of the cancer (papillary cancer) and is almost always cured. The brain. The most common brain cancers in FAP include medulloblastoma, astrocytoma and ependymoma. These are rare, even in FAP.
Can familial adenomatous polyposis skip generations?
FAP does not skip generations. In the past, neither doctors nor scientists could predict who would be diagnosed with FAP until adenomas developed in the large intestine. However, in 1991, the gene responsible for FAP was discovered and was named the Adenomatous Polyposis Coli, or APC, gene.
What causes Gardner’s syndrome?
Gardner syndrome is caused by changes ( mutations ) in the APC gene , which is called a “tumor suppressor.” Tumor suppressor genes encode proteins that are part of the system that controls cell growth and division. These proteins ensure that cells do not grow and divide too quickly or in an abnormal manner.
Does familial mean hereditary?
A familial disease is hereditary, passed on from one generation to the next. It resides in a genetic mutation that is transmitted by mother or father (or both) through the gametes to their offspring. Not all genetic disorders are familial, however, because the mutation may arise…
What does hereditary mean in health?
(heh-REH-dih-tayr-ee) In medicine, describes the passing of genetic information from parent to child through the genes in sperm and egg cells. Also called inherited.

Is familial adenomatous polyposis a rare disease?
Familial adenomatous polyposis (FAP) is a rare, inherited condition caused by a defect in the adenomatous polyposis coli (APC) gene. Most people inherit the gene from a parent. But for 25 to 30 percent of people, the genetic mutation occurs spontaneously.
Can you live with Gardner syndrome?
Intestinal polyps are the main concern for patients with Gardner syndrome because of their tendency to become cancerous. However, complete removal of the colon and most of the rectum increases the 5-year survival rate of the patients to nearly 100%.
