To determine: The probability of the child being affected by FAP if both the parents are normal but the father’s sister has experienced the FAP.
Introduction: Familial adenomatous polyposis (FAP) is a form of colorectal cancer. This cancer is a result of a mutation in a specific gene called APC gene adenomatous polyposis coli. The symptom of this type of cancer is mainly visible in the early adolescence or later stages of life. This type of cancer is autosomal dominant and requires a single allele for producing cancerous cells.
To determine: The tests that can be helpful in the assessment.
