Point Mutations in RET Proto-Oncogene Exon 10 in Patients with Medullary Thyroid Carcinoma
Background & Aims: Thyroid cancer is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) is an aggressive malignant tumor arising from parafollicular cells of the thyroid. MTC occurs in hereditary (25%, hMTC) or sporadic (75%, sMTC) forms. The hMTC form has an autosomal dominant inheritance. RET proto-oncogene mutations, especially the 10, 11, and 16 exones, are associated w...
متن کاملCellular effects and antitumor activity of RET inhibitor RPI-1 on MEN2A-associated medullary thyroid carcinoma.
BACKGROUND The RET proto-oncogene encodes a receptor tyrosine kinase. RET oncogenes arise through sporadic and inherited gene mutations and are involved in the etiopathogenesis of medullary thyroid carcinoma, a cancer that responds poorly to conventional chemotherapy. Medullary thyroid carcinoma is a component of multiple endocrine neoplasia type 2 or MEN2 syndromes. METHODS We investigated t...
متن کاملTHE MUTATIONS OF RET PROTO-ONCOGENE IN MEDULLARY THYROID CARCINOMAS IN IRAN
MeduIIary thyroid carcinoma (MTC) occurs both sporadically and in the autosomal dominantly inherited multiple endocrine neoplasia (MEN) type 2 syndromes. The distinction between true sporadic MTC and a new mutation familial case is important for future clinical management of both the patient and family. The susceptibility gene for hereditary MTC is the RET proto-oncogene. DNA analysis for g...
متن کاملRET proto-oncogene mutations in the diagnosis of medullary thyroid cancer: a review article
Medullary thyroid cancer accounts for 5-10% of thyroid carcinomas. RET proto-oncogene mutations occur in all of the hereditary MTCs and about 66% of the sporadic MTCs. So, the detection of the RET mutations is necessary for rapid and proper diagnosis and treatment. This systematic review seeks to find a comprehensive list of RET gene mutations in the diagnosis of medullary thyroid cancer. The ...
متن کاملGermline and somatic mutations in an oncogene: RET mutations in inherited medullary thyroid carcinoma.
Inherited cancer syndromes predispose an individual to development of specific tumors. Somatic and germline mutations in the same tumor suppressor gene, as described in Knudson's two-mutation model, are well recognized. Inherited mutations in the RET proto-oncogene, which encodes a receptor tyrosine kinase, predispose individuals to the multiple endocrine neoplasia type 2 (MEN 2) cancer syndrom...
