Lynch syndrome, also hereditary non-polyposis colorectal cancer syndrome (abbreviated HNPCC), is a constellation of clinical findings caused by a mutation in a mismatch repair gene, of which there are several.[1]

As the name suggests, HNPCC is a form of inherited colorectal cancer that is not characterized by abundant intestinal polyps (non-polyposis), as in adenomatous polyposis coli.

Clinical

Divided into:[1]

  • Lynch syndrome I - colon cancer associated.
  • Lynch syndrome II - non-colon cancer associated.

Associations

  • Colorectal carcinoma.
  • Non-endometrioid endometrial carcinoma.[2]
  • Stomach carcinoma.[1]
  • Biliary tree carcinoma.[1]
  • Pancreatic carcinoma.[1]
  • Urinary system carcinoma.[1]

Genes

  • MSH2 gene.[1]
  • MLH1 gene.[3]
  • PMS2 gene.[4]
  • MSH6 gene.[5]
  • Others.

Special types

Muir-Torre syndrome

Muir-Torre syndrome is a subset of HNPCC that includes the presence of sebaceous adenomas.[6] It is caused by mutations in MSH2 or MLH1.[7]
