Familial Adenomatous Polyposis (FAP)

TESTING STRATEGY

Direct mutation detection in the APC gene by a combination of sequencing and MLPA.

Presymptomatic and confirmatory testing in families with a characterised mutation. All predictive testing must be referred through a Clinical Genetics Unit to ensure that appropriate pre-test counselling and molecular genetics work-up can take place.

Linkage analysis in suitable families where an APC mutation has yet to be identified, after discussion with the laboratory.

SAMPLE REQUIREMENTS & REPORTING TIME

  • 5-10mL blood in EDTA, or DNA
  • 8 weeks for full mutation screen
  • 2 weeks for presymptomatic and confirmatory tests

FURTHER INFORMATION / LINKS

It is recommended that testing occurs only after appropriate genetic counselling by a Clinical Genetics Unit
