Familial adenomatous polyposis (FAP) is a disease with autosomal-dominant inheritance that predisposes to carcinoma of the colorectum, stomach, duodenum, and thyroid. There is increasing evidence that germline variants in APC (E1317Q) predispose to the development of multiple colorectal adenomas and carcinoma.
Germline APC mutations are characteristically associated with Familial Adenomatous Polyposis (FAP) that predisposes to carcinomas of the colo-rectum, stomach, duodenum, and thyroid. Recently somatic mutations in exon 15 of APC gene have been described in certain sporadic papillary thyroid carcinomas. The prognostic impact of these mutations remains unknown in such settings.
APC mutations have been reported in lung squamous cell carcinoma and small-cell lung carcinoma, but rarely in lung adenocarcinoma. However, variants in the APC gene have not been well characterized in lung adenocarcinoma and their clinical significance is unclear. According to ClinVar, this particular variant is a likely benign germline variant (https://preview.ncbi.nlm.nih.gov/clinvar/variation/829/).
