Camptodactyly Syndrome, Guadalajara Type 3 (CSG3) is a rare genetic disorder characterized by the permanent flexion of the fingers and toes, as well as other skeletal abnormalities. It is caused by a mutation in the gene encoding the protein filamin A, which is involved in the formation of the cytoskeleton. Symptoms of CSG3 include camptodactyly (permanent flexion of the fingers and toes), joint contractures, scoliosis, and short stature. Other features may include facial dysmorphism, intellectual disability, and hearing loss. Treatment is supportive and may include physical therapy, splinting, and orthopedic surgery.
