MEN2A

MEN2A (Multiple Endocrine Neoplasia type 2A) is a medical condition that is characterized by the occurrence of medullary thyroid carcinoma, pheochromocytoma, and parathyroid hyperplasia or adenomas. It is a form of Multiple Endocrine Neoplasia (MEN), a group of conditions that affect the body's endocrine system.

Symptoms

The symptoms of MEN2A can vary greatly from person to person. Some people may have no symptoms at all, while others may experience severe symptoms. Common symptoms include:

• High blood pressure
• Rapid heart rate
• Sweating
• Headaches
• Nervousness or anxiety
• Frequent urination
• Constipation
• Weight loss
• Fatigue

Causes

MEN2A is caused by mutations in the RET proto-oncogene. These mutations are inherited in an autosomal dominant manner, meaning that an affected person has a 50% chance of passing the condition on to each of their children.

Diagnosis

The diagnosis of MEN2A is typically made based on a combination of clinical findings and genetic testing. Genetic testing can identify mutations in the RET proto-oncogene that cause MEN2A.

Treatment

The treatment for MEN2A typically involves surgery to remove the affected glands. This can often prevent or slow the progression of the disease. Medications may also be used to manage symptoms.
