Duane anomaly-myopathy-scoliosis syndrome (DAMS) is a rare genetic disorder characterized by a combination of Duane anomaly (a type of eye movement disorder), myopathy (muscle weakness), and scoliosis (abnormal curvature of the spine). It is caused by a mutation in the CHN1 gene, which is responsible for the development of the eye muscles and the muscles of the spine. Symptoms of DAMS include limited eye movement, difficulty focusing, drooping eyelids, and difficulty swallowing. In addition, patients may experience muscle weakness, joint pain, and scoliosis. Treatment typically involves physical therapy, medications, and surgery.
