Familial adenomatous polyposis, abbreviated FAP and also known as familial polyposis coli and adenomatous polyposis coli, is a genetic condition that predisposes to adenomatous polyps and thus invariably results in colorectal cancer.
Gardner syndrome[1] is a subset of FAP. Both FAP and Gardner syndrome have a mutation in the FAP gene.[2]
Inheritance
- Autosomal dominant.
Gene
- APC gene[2] mutation.
Variants
It comes in two main flavours:
- FAP (no otherwise specified - the plain vanilla flavour).
- Many polyps - typically > 100.
- Attenuated FAP, abbreviated AFAP.
- Less polyps - typically 10 to 100.[3]
- As one my think... they tend to get cancer later than (the plain vanilla) FAP.
- Less polyps - typically 10 to 100.[3]
Gardner syndrome
Turcot syndrome
FAP associated with a medulloblastoma.[3]
Associations
Benign things:
Tumours:[3]
- Hepatoblastoma.
- Colorectal carcinoma.
- Gastric adenocarcinoma.
- Papillary thyroid carcinoma, cribriform-morular variant.[5]
Benign tumours:[3]
Prevalence
1/11,300-37,600 in Europe.[3]
See also
- Colorectal carcinoma.
- Adenomatous polyps.
- MUTYH polyposis syndrome - an autosomal recessive polyposis syndrome.
