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 .

Whether this is the same disorder as that in Menkes’ family was unclear. Changes in the metaphyses of d long bones resemble scurvy. The first report of the EEG changes in MD included four patients with multifocal spike-and-wave activity Heritable Disorders of Connective Tissue.

The patient had a missense mutation in the ATP7A gene, which the authors hypothesized may have resulted in better response to therapy than a more deleterious mutation. A newspaper photograph of the 9-year-old patient indicated his appearance at the time of the report.

Alterations in copper and collagen metabolism in the Menkes syndrome and a new subtype of the Ehlers-Danlos syndrome. Menkes disease MNKalso known as Menkes syndrome[1] [2] is an X-linked recessive disorder caused by mutations in genes coding for the copper-transport protein ATP7A[3] leading to copper deficiency.

However, in those patients in late stages of MD mitochondrial compromise oxidase c cytochrome complex ragged red fibers can be found, similar to those found in mitochondrial myopathies 18, In the intestine copper does not enter the circulation; advantage has been taken of this fact to decrease the intestinal absorption of copper by administering zinc in Wilson disease MD was first described in by Menkes et al.
