Attenuated Familial Adenomatous Polyposis

Attenuated familial adenomatous polyposis (AFAP) is a rare but well-established cause of colorectal carcinoma and multiple polyps. The present paper describes a case of a woman diagnosed with colorectal cancer at 34 years of age and subsequently found to have AFAP by genetic testing. During infancy, the patient underwent surgical correction of esophageal atresia with colonic interposition. While she had developed adenomatous polyps in her native cecum, there was no evidence of polyps or cancer in the segment of large intestine interposed between her upper esophagus and stomach. Therefore, various environmental differences between the upper and lower gastrointestinal tract may play a role in the expression of AFAP phenotype.

Revised Bethesda Guidelines

Abstract Precancerous polyposes other than classic familial adenomatous polyposis and the condition hereditary nonpolyposis colorectal cancer, or Lynch syndrome, continue to present major diagnostic challenges for the anatomic pathologist. This editorial highlights the practical significance of novel insights and clinical guidelines in the recent literature, as well as in 4 contributions to this edition of the Archives of Pathology & Laboratory Medicine. The first section will address attenuated familial adenomatous polyposis and a newly recognized type of autosomal-recessive adenomatous polyposis associated with the DNA repair gene MYH. The remainder of the editorial discusses the role of the revised Bethesda guidelines in the diagnosis of hereditary nonpolyposis colorectal cancer and concludes with the recently identified serrated pathway syndrome.

Apc Mutation

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome associated with mutation in the adenomatous polyposis coli (APC) gene, a tumour suppressor located on chromosome 5q21. Attenuated familial adenomatous polyposis (AFAP) is a variant associated with fewer and later onset of colon polyps. AFAP-associated APC mutations have largely been found before codon 157, in exon 9 or after codon 1595. We present the case of a 44-year-old man incidentally found to have numerous gastric polyps during bariatric surgery, with innumerable polyps in the remaining part of the stomach and the entire colon, with rectal sparing, consistent with AFAP phenotype. Genetic testing demonstrated the c.7682dup (p.Ser2562Lysfs*21) variant in exon 15 of APC. This represents a previously undescribed APC mutation. This mutation likely yields end-binding protein 1 and human disc large binding protein inactivation, causing cell cycle microtubule dysregulation and tumour suppressor inactivation. Through loss of these regulatory mechanisms, this mutation is associated with AFAP phenotype. The patient was treated surgically and is doing well.
