Carpenter syndrome is a condition characterized by premature fusion of skull bones (craniosynostosis); finger and toe abnormalities; and other developmental problems. The features in affected people vary. Craniosynostosis can give the head a pointed appearance; cause asymmetry of the head and face; affect the development of the brain; and cause characteristic facial features. Other signs and symptoms may include dental abnormalities; vision problems; hearing loss; heart defects; genital abnormalities; obesity; various skeletal abnormalities; and a range of intellectual disability. Carpenter syndrome can be caused by mutations in the RAB23 or MEGF8 gene and is inherited in an autosomal recessive manner. Treatment focuses on the specific features in each affected person. Life expectancy is shortened but very variable.
