Awareness of hereditary colorectal cancer syndromes is important to facilitate their identification because affected patients are at increased risk for early onset, synchronous, and metachronous colorectal malignancies, and certain extracolonic malignancies depending on the syndrome. There are known gene mutations that lead to hereditary colon cancer syndromes. The cancer risk in jps is believed to arise from adenomatous tissue within the juvenile polyp, as up to 50% of juvenile polyps in jps contain areas of adenomatous change. It is caused by genetic mutations in dna mismatch repair (mmr) genes, notably mlh1, msh2, msh6 and pms2. Most patients with an inherited colorectal cancer syndrome are not diagnosed until the development of a colorectal neoplasm. Lynch syndrome has historically been known as hereditary nonpolyposis colorectal cancer (hnpcc). People with lynch syndrome also have an increased risk of cancers of the stomach, small intestine, liver, gallbladder. Mutations (changes) in several different genes can cause hereditary syndromes that increase the risk of renal cell cancer.genes are pieces of dna that contain information needed to define traits and genetic conditions. Genetic counseling and testing are important to identify patients and family members with hereditary colon cancer syndromes so that screening with flexible sigmoidoscopies and colonoscopies can begin early and, if necessary, the colon can be removed surgically to prevent colon cancer. Chromosomes have proteins called histones that bind to dna. In addition to colorectal cancer many other cancers are increased in frequency. 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. Most hereditary cancer syndromes exhibit autosomal dominant inheritance. A hereditary cancer syndrome is a genetic predisposition to certain types of cancer, often with onset at an early age, caused by inherited pathogenic variants in one or more genes. Here are the most common. The initial assessment is the collection of a family history of cancers and premalignant gastrointestinal conditions and should provide enough information to develop a preliminary determination of the risk of a familial predisposition to cancer. The two major subtypes of hereditary colon cancer are called familial adenomatous polyposis (fap) and lynch syndrome, also known as hereditary.

The mean age of colon cancer is 34 years, with a range of 15 to 68 years. Since some polyposis syndromes like afap or map may not present with a significant personal/family history of colon cancer or colon polyps, genetic testing may be a useful tool to identify at risk individuals. These changes are known as hereditary cancer syndromes.

Familial adenomatous polyposis (fap) is an inherited disorder characterized by cancer of the large intestine and rectum.people with the classic type of familial adenomatous polyposis may begin to develop multiple noncancerous (benign) growths in the colon as early as their teenage years.unless the colon is removed, these polyps will become malignant (cancerous).

There are multiple hereditary colorectal cancer syndromes known with respective associated genetic mutations, cancer risks, and screening and prevention recommendations. For example, breast cancer and ovarian cancer run together in families with hereditary breast and ovarian cancer syndrome (hboc). Specific criteria for the diagnosis of the various syndromes are included in the discussion of the specific entities, but, in general, a hereditary colorectal cancer syndrome should be suspected in patients with either an unusually large number of colon polyps.
