Frequently Asked Questions

QWhat exactly is Multiple Hereditary Exostoses?

Multiple Hereditary Exostoses (MHE) is a rare genetic disorder characterized by the growth of noncancerous bone tumors, known as exostoses or osteochondromas, near the growth plates of bones. These growths can lead to pain, deformities, and, in some cases, can impact the growth and development of bones.

QHow do people inherit MHE?

MHE is passed down through families in an autosomal dominant pattern. This means if one parent has the condition, there's a 50% chance their child will inherit it. Mutations in the EXT1 or EXT2 genes are often responsible for causing this disorder.

QCan MHE lead to cancer?

While the bone growths associated with MHE are typically benign, there's a small risk they could become malignant. The risk of one of these osteochondromas transforming into a chondrosarcoma, a type of bone cancer, is estimated to be low but notable, especially in adults.

QAre there treatments available for MHE?

Yes, treatments focus on managing symptoms and preventing complications. Surgical removal of painful or problematic exostoses is common. Physical therapy can also help maintain mobility and muscle strength. However, there's currently no cure for the underlying genetic condition.
