Abstract excerpt
Pathogenic germline variants in the APC gene result in familial adenomatous polyposis (FAP) which can escalate into colon cancer. Standard clinical testing failed to identify pathogenic variants in a 4-generation FAP family. We identified and assessed co-segregation of a 5' untranslated region (UTR) variant, NM_001127511.3 (APC) c.-40G>A (GRCh37 chr5:112043375) that creates a potential out-of-frame AUG start...
