Menkes syndrome

kink·y-hair dis·ease

, kinky hair disease [MIM*309400] an inborn error of copper metabolism, onset within a few weeks of birth; manifested by short, sparse, poorly pigmented kinky hair; failure to thrive; development of seizures; spasticity; and progressive mental deterioration leading to death. X-linked recessive inheritance due to a defect of copper transport, caused by mutation in the Menkes gene (MNK), which encodes a copper-transporting ATPase on Xq. Synonym(s): Menkes syndrome, trichopoliodystrophy

ATP7A

A gene on chromosome Xq21.1 that encodes a transmembrane protein that functions in copper transport across membranes, localising to the trans-Golgi network.
Molecular pathology
ATP7A mutations cause Menkes disease, occipital horn syndrome and X-linked cutis laxa.
