NIH Rare Diseases:42 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. last updated: 2/2/2012

MalaCards: Occipital Horn Syndrome, also known as cutis laxa x-linked, is related to menkes disease and intracranial aneurysm, and has symptoms including scoliosis, kyphosis and narrow/sloping shoulders. An important gene associated with Occipital Horn Syndrome is ATP7A (ATPase, Cu++ transporting, alpha polypeptide), and among its related pathways is Elastic fibre formation. The compounds beta-aminopropionitrile and alpha-aminoadipic semialdehyde have been mentioned in the context of this disorder. Affiliated tissues include skin and bone, and related mouse phenotypes are respiratory system and muscle.
