Lynch syndrome can be caused by mutations in the MLH1, MSH2 and MSH6 genes. Such mutations are also linked to cancers of the endometrium, stomach, small bowel, ureter, ovary and collecting system of the kidneys.

For example, hereditary colon cancer may be due to familial adenomatous polyposis (FAP), Lynch syndrome, Peutz-Jeghers syndrome, juvenile polyposis syndrome, or other syndromes. Each of these has a different genetic basis.

Hereditary non-polyposis colorectal cancer (HNPCC) is also known as Lynch syndrome. HNPCC may be a possible diagnosis when there are multiple cases of colorectal cancer on the same side of the family.
