The abnormality of the skull bones causes changes in the shape of the face and head. Most affected individuals also have differences to their midface and conductive hearing loss. This syndrome also affects bones in the hands and feet. It’s also referred to as acrocephalosyndactyly type V, ACSV, craniofacial-skeletal-dermatologic syndrome, and Noack syndrome [1-3].
