Adenomatous Polyposis Families That Screen APC Mutation–Negative by Conventional Methods Are Genetically Heterogeneous
18 Aug 2005
Abstract excerpt
PURPOSE: One third of families with classical adenomatous polyposis (FAP), and a majority of those with attenuated FAP (AFAP), remain APC mutation-negative by conventional methods. Our purpose was to clarify the genetic basis of polyposis and genotype-phenotype correlations in such families. PATIENTS AND METHODS: We studied a cohort of 29 adenomatous polyposis families that had screened APC mutation-negative by...
