CLINICAL UTILITY
Lynch syndrome (LS), also known as hereditary nonpolyposis colorectal cancer (HNPCC), is a hereditary cancer syndrome that predisposes individuals to colorectal, endometrial, ovarian, stomach, small bowel, and other cancers. LS is caused by a single pathogenic variant in a mismatch repair (MMR) gene (MLH1, MSH2, MSH6, PMS2) or a pathogenic deletion in the EPCAM gene leading to MSH2 inactivation.

The patient can provide blood sample in EDTA
Recommended test for individuals with a personal and/or family history consistent with Lynch syndrome when documentation of a causative familial variant is not available
The test is performed by NGS technique
There is no risk associated as blood sample is required in EDTA vacutainer
The test is reported as pathogenic mutation detected (Positive) No pathogenic variants detected (Negative) and Inconclusive
Variant of uncertain clinical significance detected
