Medical position statement: hereditary colorectal cancer and genetic testing (pdf). The majority of individuals with Lynch syndrome inherited a pathogenic variant from a parent; however, because of incomplete penetrance, variable age of cancer development, cancer risk reduction as a result of screening or prophylactic surgery, or early death, not all individuals with a pathogenic variant in one of the genes associated with Lynch syndrome have a parent who had cancer.
