摘要: Background: Germline RET gene mutations are causative of multiple endocrine neoplasia (MEN) 2 and may be identified by genetic screening. Three different syndromes distinguished: MEN 2A, when medullary thyroid carcinoma (MTC) is associated with pheochromocytoma and/or parathyroid adenomas; 2B, accompanied a marfanoid habitus pheochromocytoma; familial (FMTC), only MTC present. Patients Methods: During the last 13 yr, we performed screening in 807 subjects: 481 apparently sporadic MTC, 37 clinical evidence 2, 289 relatives. Genomic DNA was extracted from blood all subjects, exons 10, 11, 13, 14, 15, 16 were analyzed direct sequencing after PCR. Results: We unexpectedly discovered germline mutation 35 (7.3%) patients. A also found 36 patients hereditary MTC. The distribution ...
