We report the existence of both germline and somatic mutations of the APC gene in thyroid carcinomas from familial adenomatous polyposis (FAP) patients. One papillary thyroid carcinoma from a 210-year-old woman, with germline mutation of the APC gene (TCA to TGA at codon 1110), showed a somatic mutation of AAAAC deletion between codons 1060 and 1063. Another somatic mutation of CAG to TAG at codon 886 was also found in one of multiple thyroid carcinomas from a 26-year-old woman with attenuated FAP and germline mutation at codon 175 (C deletion). This is the first evidence that total absence of the normal function of the APC gene is involved in development of thyroid carcinomas in FAP.
我们报告了家族性腺瘤性息肉病(FAP)患者甲状腺癌中存在APC基因的种系突变和体细胞突变。一名21岁女性的甲状腺乳头状癌,其APC基因存在种系突变(密码子1110处TCA突变为TGA),在密码子1060和1063之间显示出AAAAC缺失的体细胞突变。在一名26岁患有轻度FAP且密码子175处存在种系突变(C缺失)的女性的多个甲状腺癌中的一个中,还发现了密码子886处CAG突变为TAG的另一个体细胞突变。这是首次有证据表明APC基因正常功能的完全缺失与FAP患者甲状腺癌的发生有关。
