1 doctor agrees

In brief: No

The familial adenomatous polyposis (fap) gene (apc) exhibits dominant inheritance where affected individuals have one normal and one abnormal copy of the gene.
A person can have fap due to a new apc gene mutation (without their parents having it) but this gene would be present at conception.
