ENFERMEDAD DE MENKES PDF

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 .

Genetic disordermembrane: No adverse effects of pamidronate treatment were noted. This finding supported localization of the MNK locus to Xq13 and suggested fine mapping to subband Xq The EMG pattern has not yet been established in MD because exist few studies focus on the electrophysiological abnormalities in this disorder.

OMIM Entry – # – MENKES DISEASE

Serum copper levels were decreased in 2 patients and low-normal in the third patient. The lack of copper may result in these changes, as copper is a key cofactor in the mitochondrial respiratory chain 18, By then aged 10 years, the patient had been treated for many years with injections of copper histidinate. Tumer and Horn reviewed the clinical and genetic aspects of Menkes syndrome, including phenotypic expression in females, mutation spectrum, diagnosis, and treatment.

Changes in the metaphyses of the long bones resemble scurvy. 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.

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, From Wikipedia, the free encyclopedia.

Fabio Agertt; Ana C. Early development of occipital horns in a classical Menkes patient.

Copper accumulates in some tissues, such as the small intestine and kidneyswhile the brain and other tissues have unusually low levels. Comparative mapping suggested to Horn et al. Most aneurysms occurred in the ascending aorta, with some also present in mdnkes descending thoracic and abdominal segments.

Effects of Deficiency and Overload”. Hypocalcaemia Osteomalacia Pseudohypoparathyroidism Albright’s hereditary osteodystrophy Pseudopseudohypoparathyroidism. In support of this hypothesis, Kelly and Palmiter found that cell lines derived from metallothionein deficient, Mottled embryos were very sensitive to copper toxicity. Muscle strength was slightly diminished, deep tendon reflexes were increased with extension plantar reflex response.

However, in 2 unrelated patients with this disorder who were born prematurely and received early copper-histidine treatment, the response was favorable see Sherwood et al.
