Video Summary
Multiple endocrine neoplasias, or MEN for short, are a group of inherited diseases that cause tumors to grow in the endocrine glands of the body. MEN tumors are classified into two broad categories based on their underlying mutations. There is MEN1 caused by a mutation in the MEN1 gene, and MEN2, which is caused by a mutation in the RET gene.
People with MEN1 present with tumors in the pituitary gland or parathyroid glands and pancreatic tumors. MEN2 is further divided into two subtypes: MEN2A and MEN2B. MEN2A is characterized by medullary thyroid cancer, pheochromocytoma, and parathyroid tumors; whereas MEN2B presents with medullary thyroid cancer, pheochromocytoma, and mucosal neuromas.
