Overview
Medullary thyroid cancer (MTC) is a rare form of thyroid cancer accounting for about 10 % of all thyroid malignancies. It occurs mostly as a sporadic tumour or in association with autosomal dominant inherited cancer syndromes - multiple endocrine neoplasia (MEN) types 2A and 2B and familial MTC. Germline mutations in the RET proto-oncogene were found in most of the familial cases. Here we describe molecular genetic detection in one MEN2A family with three generations, where we found a double germline mutation in exons 10 (Cys620Phe) and 13 (Tyr791Phe) of the RET proto-oncogene.
Key words:
medullary thyroid cancer, molecular genetics, MEN2A syndrome, RET proto-oncogene.
