Article Title: Variable phenotypic expression of identical MYH germline mutations in siblings with attenuated familial adenomatous polyposis
Abstract: Germline mutations in the Mutant-Y-homologue (MYH) gene have been linked to an attenuated form of familial adenomatous polyposis in patients who express a wild-type adenomatous polyposis coli gene. However, the diverse clinical manifestations of MYH mutations have not been fully elucidated. We report a case of siblings with identical germline mutations in the MYH gene, one of whom developed a locally advanced colon adenocarcinoma with few other adenomatous lesions, whereas the other had numerous benign colonic polyps. The variable genotype-phenotype manifestations of MYH mutations and the attenuated familial adenomatous polyposis syndrome are discussed.
