Apert syndrome is a rare genetic disorder that affects the development of the skull, face, and hands. It is also known as acrocephalosyndactyly or ACS. The condition is characterized by the early closure of bones in the skull, causing the head to appear pointed. The face may also be affected, with eyes that bulge and typically close partially. The hands and feet may be fused together, leading to limited mobility. Other synonyms for Apert syndrome include congenital craniosynostosis, craniocarpotarsal dysplasia, and craniofacial dysostosis. Despite the various names, the symptoms and effects of Apert syndrome remain the same. Treatment options depend on the severity of the condition and may include surgery to correct physical deformities.
