摘要家族性腺瘤性息肉病(familial adenomatous polyposis,FAP)以结直肠内生长成百上千枚息肉为主要特征,不进行治疗的患者几乎100％发展成大肠癌,主要由腺瘤性息肉病基因(adenomatous polyposis coli,APC)突变所致,越来越多学者发现APC基因突变位点和FAP临床表现具有一定相关性.本文将从FAP的分型、临床表现、诊断标准、致病基因APC、基因-表型相关性及治疗监测等方面作一综述.

abstractsFamilial adenomatous polyposis (FAP) is a common hereditary syndrome that is characterized by the numerous adenomatous polyps in the colon and rectum,and almost all patients will develop colorectal cancer without treatment.It is mainly caused by a germline mutation of adenomatous polyposis coli (APC) gene,and more and more studies have attempted to correlate the location of the mutations on APC gene with clinical phenotypes.The aim of this review is to summarize the current clinical and genetic knowledge of FAP and the genotype-phenotype correlations.
