McCune-Albright syndrome

Overview

McCune-Albright syndrome is a rare genetic disorder that affects different parts of the body. It can cause a variety of symptoms, such as abnormal bone growth, skin pigmentation, and hormonal imbalances. This syndrome is caused by changes in a gene called GNAS, which leads to cells producing too much of a protein called cAMP.

People with McCune-Albright syndrome may experience bone pain, fractures, and deformities due to the abnormal bone growth. They may also have skin patches with irregular pigmentation, known as café-au-lait spots. Additionally, hormonal imbalances can cause early puberty in children, as well as other problems like thyroid abnormalities or excessive growth hormone production. Treatment for McCune-Albright syndrome focuses on managing the symptoms and complications that arise, such as surgery for bone abnormalities or medications to regulate hormone levels.
