Implication of molecular genetic examination in a Ihree generational family with multiple endoerine neoplasia type 2A

Abstract
Medullary thyroid cancer (MTC) is a rare form of thyroid cancer accounting for about 10 % of all thyroid malignancies. It oceurs mostly as a sporadic tumour or in association with autosomal dominant inherited cancer syndromes - multiple endoerine neoplasia (MEN) types 2A and 2B and familial MTC.
Germline mutations in the RET proto-oneogene were found in most of the familial cases. Here we deseribe molecular genetic detection in one MEN2A family with three generations, where we found a double germline mutation in exons 10 (Cys620Phe) and 13 (Tyr791 Phe) of the RET proto-oneogene.
