Craniometaphyseal Dysplasia, Autosomal Dominant
Autosomal dominant craniometaphyseal dysplasia is a genetic skeletal condition characterized by progressive thickening of bones in the skull (cranium) and abnormalities at the ends of long bones in the limbs (metaphyseal dysplasia). The overgrowth of bones in the head can lead to distinctive facial features and delayed tooth eruption, as well as compression of the cranial nerves. If untreated, compression of the cranial nerves can be disabling. The condition is caused by mutations in the ANKH gene. As the name suggests, it is inherited in an autosomal dominant manner. Treatment may include surgery to reduce compression of cranial nerves and recontouring of the facial bones.
