Caffey disease

Disease Overview

Caffey disease is a bone disorder that most often occurs in babies. It is characterized by the excessive formation of new bone (hyperostosis) in the jaw, shoulder blades, collarbones, and shafts of long bones in the arms and legs. Affected bones may double or triple in width. In some cases, two bones that are next to each other may become fused. Caffey disease is caused by a mutation in the COL1A1 gene. It is inherited in an autosomal dominant pattern, but not all people who inherit the mutation develop signs and symptoms. This is due to incomplete penetrance.[7344]
