MEN2B or Multiple Endocrine Neoplasia Type 2B is a rare autosomal dominant genetic condition that primarily affects the endocrine system. It is characterized by the development of medullary thyroid carcinoma, pheochromocytoma, and multiple mucosal neuromas. MEN2B is a subtype of Multiple Endocrine Neoplasia (MEN), a group of medical disorders that affect the body's endocrine system.
Symptoms[edit]
The most common symptoms of MEN2B include:
- Medullary thyroid carcinoma
- Pheochromocytoma
- Mucosal neuromas
- Marfanoid habitus
- Intestinal ganglioneuromatosis
Genetics[edit]
MEN2B is caused by mutations in the RET gene. This gene provides instructions for producing a protein that is involved in signaling within cells. Mutations in the RET gene can lead to the development of tumors in the endocrine system.
Diagnosis[edit]
Diagnosis of MEN2B is based on clinical features, family history, and genetic testing. Genetic testing can confirm a diagnosis and identify family members who carry the mutation.
Treatment[edit]
Treatment for MEN2B typically involves surgery to remove the affected glands. Medications may also be used to manage symptoms.
