Wikipedia. Instance of, disease, Designated intractable/rare diseases. Subclass of, hair disease, metal metabolism disorder. Menkes disease (MNK), also known as Menkes syndrome, is an X-linked recessive disorder caused by mutations in genes coding for the copper-transport . A number sign (#) is used with this entry because of evidence that Menkes disease is caused by mutation in the gene encoding Cu(2+)-transporting ATPase .

Onset occurs during infancy, with incidence of about 1 intonewborns; affected infants often do not live past the age of three years, though there are rare cases in which less severe symptoms emerge later in childhood.

Copper-histidine therapy for Menkes disease.

Occipital horn syndrome sometimes called X-linked cutis laxa or Ehlers-Danlos type 9 [9] is a mild form of Menkes syndrome that begins in early to middle childhood. Features were somewhat variable, but included hypotonia, myopathic facies, coarse hair, silvery hair, skin and joint laxity, and severe global developmental delay.

Defective metallothionein see was suggested. Conditions of the skin appendages Inborn errors of metal metabolism Rare diseases X-linked recessive disorders Syndromes Syndromes affecting the nervous system. Enefrmedad of the skull and skeleton are conducted to look for abnormalities in bone formation.

In studies of 4 families in which a characteristic X-centromeric marker was segregating with Menkes disease, Friedrich et al. Microscopically it showed twisting, varying diameter along the length of the shaft, and often fractures of the shaft at regular intervals. The treatment options are limited because the brain-blood barrier acts as an obstacle to copper delivery without the transporter protein 1,2,5,16, He suffered from persistent chronic diarrhea since early infancy.

On the electroencephalogram EEG there was an abnormally disorganized background activity without any predominance of side, intermingled with highly active epileptic activity, mostly over the parieto-rolandic areas bilaterally, which was immediately followed by diffuse voltage depression.

Copper deficiency in animals leads to connective tissue changes because formation of lysine-derived cross-links in elastin and collagen is interfered with, the amine oxidase responsible for the initial modification of lysine being copper-dependent.

The occipital horn syndrome is caused by mutation in the same gene. A sex-linked recessive disorder with retardation of growth, peculiar hair, and focal cerebral and cerebellar degeneration. This prevents the production of a functional ATP7A protein, leading to the impaired absorption of copper from food and copper will not be supplied to certain enzymes.
