Multiple endocrine neoplasia type 2

Multiple endocrine neoplasia type 2 is a group of medical disorders associated with tumors of the endocrine system. The tumors may be benign or malignant (cancer). They generally occur in endocrine organs, but may also occur in endocrine tissues of organs not classically thought of as endocrine. MEN2 is a sub-type of MEN and itself has sub-types, as discussed below. Variants in MEN2A have been associated with Hirschsprung disease. Screening for this condition can begin as young as eight years old for pheochromocytoma.
