Multiple endocrine neoplasia type 2 (also known as " Pheochromocytoma (codons 630 and 634) and amyloid producing medullary thyroid carcinoma", [ 1] "PTC syndrome," [ 1] and "Sipple syndrome" [ 1]) is a group of medical disorders associated with tumors of the endocrine system. The tumors may be benign or malignant ( cancer ).
RET receptor defect Which is growth signal receptor, its type of self-sufficiency of growth signals.

Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [ 1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [ 2] MTC was first characterized in 1959.
RET loss of function mutations are associated with the development of Hirschsprung's disease, [6] [7] while gain of function mutations are associated with the development of various types of human cancer, including medullary thyroid carcinoma, multiple endocrine neoplasias type 2A and 2B, pheochromocytoma and parathyroid hyperplasia.
