MEN type 1, or Multiple Endocrine Neoplasia type 1, is a rare genetic disorder that affects the endocrine system. It is characterized by the development of tumors in multiple glands, particularly the pituitary gland, parathyroid glands, and pancreas. These tumors can lead to hormonal imbalances and various health issues. The condition is inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene from an affected parent can cause the disorder in their offspring. Early diagnosis and management are crucial to monitor and treat the tumors effectively, helping to prevent complications associated with hormone overproduction.
