COLARIS® is a genetic test that assesses a person’s risk of developing hereditary colorectal cancer and a woman’s risk of developing hereditary uterine (endometrial) cancer. Using a simple blood test or oral rinse sample, COLARIS® detects disease-causing mutations in the MLH1, MSH2, EPCAM, MSH6, PMS2 and MYH genes that are responsible for the majority of Lynch syndrome and MYH-associated polyposis (MAP) cases.
Myriad has developed a Hereditary Cancer Quiz that patients and physicians can use to help identify potential candidates for genetic testing using COLARIS.
Lynch syndrome, also known as Hereditary Nonpolyposis Colorectal Cancer (HNPCC) syndrome, is the most common of the hereditary colon cancer syndromes and is believed to account for three to five percent of all colorectal cancers. COLARIS® is a genetic test for Lynch syndrome. Knowing the results of the COLARIS® test may help patients and their healthcare professionals take steps to prevent cancer before it has a chance to develop.
MYH-associated polyposis (MAP) is caused by mutations in the MYH gene. Individuals with MAP have mutations in both of their MYH genes (one from each parent, often referred to as “biallelic MYH mutations”). Patients often have no family history of colon cancer or polyps in their parents (although siblings may be affected).1 The MYH gene is an important part of the base excision repair (BER) pathway, which allows for repair of DNA mutations caused by oxidative damage to cells.
The results of the COLARIS®test enable patients and their healthcare professionals to develop individualized medical management plans to significantly reduce the risk of cancer. COLARIS® helps healthcare professionals to:
Once a diagnosis of Lynch syndrome or MAP is confirmed, the following medical management options may help reduce the risk of cancer or detect it at an earlier, more treatable stage:
