Technical Information
Test Comments: Help
The testing strategy for Lynch syndrome includes screening by MSI analysis followed by immunohistochemistry (IHC) testing of MMR proteins. Full gene sequencing and deletion/duplication analysis can then be performed to identify germline mutations in the putative mutated gene(s) identified by IHC.
