Occipital horn syndrome
Cutis laxa, x-linked
Type of disease: Rare conditions
Occipital horn syndrome (OHS) is characterized by sagging and non-stretchy skin (cutis laxa), wedge-shaped calcium deposits in a bone at the base of the skull (occipital bone), coarse hair, and loose joints. Individuals with OHS are said to have normal or slightly reduced intelligence. This condition is considered to be a mild type of Menkes diseases, which affects copper levels in the body. Occipital horn syndrome may be caused by mutations in the ATP7A gene, and it is inherited in an x-linked recessive pattern.
