Relationships between adenomatous polyposis coli (APC) mutations, BRAF V600E mutations, and the CpG island methylator phenotype (CIMP) in colon cancer have not been explored.
We report a case with a very rare deletion mutation of BRAF (c.1799-1801delTGA, p.Val600_Lys601delinsGlu) in a serrated adenoma; the patient has familial adenomatous polyposis with a germline mutation of the APC gene (c.3578delA, p.Gln1193ArgfsX1264).
