MEN type 2, or Multiple Endocrine Neoplasia type 2, is a genetic disorder that affects the endocrine system, leading to the development of tumors in multiple glands. It is primarily associated with tumors in the thyroid, parathyroid, and adrenal glands. There are three subtypes: MEN 2A, MEN 2B, and familial medullary thyroid carcinoma, each with distinct features and risks. The condition is caused by mutations in the RET gene, which plays a crucial role in cell signaling and growth. Early diagnosis and management are essential to prevent complications, as affected individuals may experience symptoms related to hormone imbalances or tumor growth. Regular monitoring and surgical interventions are common treatment approaches.
