Summaries for Occipital Horn Syndrome

About this section
NIH Rare Diseases:45 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 based summary: Occipital Horn Syndrome, also known as cutis laxa x-linked, is related to menkes disease and breast cancer, and has symptoms including abnormality of the fontanelles or cranial sutures, hyperextensible skin and joint hypermobility. An important gene associated with Occipital Horn Syndrome is ATP7A (ATPase, Cu++ Transporting, Alpha Polypeptide). Affiliated tissues include bone, skin and liver, and related mouse phenotype integument.

UniProtKB/Swiss-Prot:67 Occipital horn syndrome: An X-linked recessive disorder of copper metabolism. Common features are unusual facial appearance, skeletal abnormalities, chronic diarrhea and genitourinary defects. The skeletal abnormalities include occipital horns, short, broad clavicles, deformed radii, ulnae and humeri, narrowing of the rib cage, undercalcified long bones with thin cortical walls and coxa valga.
