Abstract excerpt
BACKGROUND: The phenotypic spectrum of familial adenomatous polyposis (FAP) varies from the classic appearance of hundreds of adenomatous colonic polyps in the young adult and early onset colorectal cancer, to the occurrence of sparse adenomas in the older adult, "attenuated" FAP, due to mutations at the 5' or 3' ends of the APC gene. AIMS: To investigate marked intrafamilial phenotypic variation occurring in a...
