MUTYH-associated polyposis (MAP) is a rare inherited condition characterized by a greatly increased risk of developing colorectal cancer. People with MAP have a tendency to develop multiple adenomatous colon polyps during their lifetime, which increases their risk of cancer.
An adenomatous polyp is a place in the colon where normal cells form a mass. These polyps start off as benign, meaning they are not cancerous and will not spread. However, some polyps can become malignant (cancerous) and spread around the body.
Take this test to find out whether you are at risk. Polyp removal and routine monitoring is key to minimizing colorectal cancer risk in those with MAP.
MAP is caused by genetic variation in the MUTYH gene. MAP is inherited in an autosomal recessive manner, which means two variant copies of the MUTYH gene are necessary to increase the cancer risk.
This report detects two MUTYH variants that disrupt the function of MYH glycosylase, leading to a buildup of DNA errors, which increases the risk of normal cells becoming cancerous. They account for 80-90% of cancer-related MUTYH variants in people of Northern European descent.
Understanding your genetic risk for MAP is important because routine monitoring is key to minimizing colorectal cancer risk.
