Sclerosteosis

From WikiMD's Wellness Encyclopedia

Sclerosteosis is a rare genetic disorder characterized by abnormal bone growth. It is caused by mutations in the SOST gene, which is involved in the regulation of bone formation. The condition is primarily found in the Afrikaner population of South Africa, where it has a prevalence of about 1 in 100,000.

Symptoms and Signs[edit | edit source]

The symptoms of sclerosteosis typically become apparent in early childhood. They include:

Causes[edit | edit source]

Sclerosteosis is caused by mutations in the SOST gene, which is located on chromosome 17. This gene provides instructions for making a protein that regulates bone formation. Mutations in the SOST gene lead to an overproduction of bone, resulting in the symptoms of sclerosteosis.

Diagnosis[edit | edit source]

The diagnosis of sclerosteosis is typically based on the characteristic physical features and confirmed by genetic testing. Imaging studies such as X-rays and CT scans can also be used to assess the extent of bone overgrowth.

Treatment[edit | edit source]

There is currently no cure for sclerosteosis. Treatment is aimed at managing the symptoms and may include surgery to relieve pressure on the brain and nerves caused by bone overgrowth.
