The copper injections can be administered in three ways, under the skin, in the muscle, or directly into the vein. Epilepsy is a common neurological condition in adults and children.1 It affects more than 1% of the population worldwide.2,3 In Saudi Arabia, its prevalence is 6.54/1000 population. Google Scholar, Culotta VC, Gitlin JD, et al: Disorders of copper metabolism in Scriver CR et.el. Variants of Menkes that are caused by mutations in the ATP7A gene but result in less severe symptoms include mild Menkes disease and occipital horn syndrome. These abnormalities are associated with a severe reduction in the activity of lysyl oxidase, the extracellular copper enzyme that initiates crosslinking of collagens and elastin. Menkes disease usually causes low copper levels in blood plasma, the liver and the brain. The Menkes protein is a transmembrane copper translocating P-type ATPase. These infarctions may play an unrecognized but important role in the neurodegeneration of children with Menkes’ disease. Found insideThe fourth edition of this authoritative text covers every aspect of liver disease affecting infants, children and adolescents. The copper deficiency leads to severe brain damage and neuromuscular deficits. The Menkes copper transporter is required for the activation of tyrosinase.

The deficiency or impaired function of these enzyme systems is thought to be responsible for the clinical findings of Menkes disease. The copper deficiency leads to severe brain damage and neuromuscular deficits. Nervous system problems include gross mental retardation, convulsions, cortical atrophy, asymptomatic subdural effusion, grosss trunkal hypotonia and progressive neurological deterioration, Vascular problems with weak collagen tissues causes easy breakability, connective tissue abnormality gives rise to characteristics steel, fuzzy, wooly, sparse hair with easy pluckability [2]. 70/50 mm Hg, respiratory rate 55/min, temperature – normal. 11. Cases Journal © 2021 BioMed Central Ltd unless otherwise stated. Copper must then be delivered to brain cells and be available for use by enzymes. This is a degenerative disorder of the body’s copper metabolism, which causes a deficiency of copper in the cells of the body, leading to retardation and stunted growth (12). Copper is vital for numerous cellular functions affecting all tissues and organ systems in the body. The authors declare that they have no competing interests. [Bsc Biological Chemistry] Both wilsons and Menkes disease are recessive disorders whose occurrence is solely down to a mutation in the copper transporting channels of ATP7A or ATP7B respectively. An eight month old male infant with protein energy malnutrition was admitted in the hospital with the history of repeated attacks of convulsion since four months of age. Found insideMost strokes are attributed to atherosclerosis of neck and intracranial arteries, brain embolism from the heart, and penetrating artery disease; these are discussed in detail in many other books. The MRI study of the brain revealed prominent bilateral extra-axial C.S.F. Menkes patients exhibit symptoms consistent with hypoactivity of copper-dependent enzymes, including severe mental retardation associated with neurodegeneration and sei-zures, reduced melanin pigmentation, and impaired extracellu-lar matrix formation. The Menkes disease gene is (ATP7A) encodes an enzyme p type ATPase which is required for systemic absorbtion, distribution and metabolism of copper in tissues. The bones are osteopenic. The investigation finding of low serum copper, ceruloplasmin, hair structures are characteristics of Menkes disease[8]. Menkes Disease (MNK), also commonly known as Menkes Syndrome, Copper Transport Disease and Steely Hair Disease, Kinky Hair Disease or Menkes Kinky Hair Syndrome is a rare X-linked recessive neurodegenerative disorder caused by a mutation in the ATP7A copper-transporting ATPase gene.

The mother also informed that her baby was lagging in growth and development in comparison to the other children of same age and sex in the community. MRI studies are supportive of the disease. Help. Young children with the disorder typically die within three years of life due to a genetic mutation that limits their body’s ability to absorb and utilize copper from their diet. menkes disease. Other systems appeared normal. Copper accumulates at abnormally low levels in the liver and brain, but at higher than normal levels in the kidney and intestinal lining. Mollar LB, Tumer Z, Lund C, et al: Similar splice-site mutation s of ATP7A gene lead to different phenotypes: classical Menkes disease or occipital horn syndrome. The major breakthrough came when their group came up with a new way to prepare the drug. The skeletal survey of the limb bones also showed osteopenia. Because of lack of facility, genetic study is not possible in this case. 2002, 39: 183-185. Menkes patients suffer from neurological and connective tissue abnormalities as a result of copper deficiency, which reduces the activity of copper-depend-ent enzymes (9). ATP7A normally contributes to numerous neurological functions, and so its absence or deficiency leads to impaired neurodevelopment and extensive neurodegeneration. There are chances of recurrent infections and as a result the infant fails to thrive and malnutrition is a common finding [3]. Found insideThis book presents a systematic and comprehensive revision about NAFLD, highlighting its epidemiological and molecular aspects, as well as its prevention and treatment.

It brings broad coverage of the topic using many color images to illustrate key points. Gohil began working on this project in 2012, and in 2014 his team began focusing on elesclomol and showed that it can deliver copper to mitochondria and restore the production of cytochrome oxidase protein complex in copper-deficient yeast and human cells, as well as in zebrafish. Datta, A.K., Ghosh, T., Nayak, K. et al. The serum copper concentration is low. Menkes disease is an X-linked lethal multi system disorder caused by disturbances of copper distribution in different tissues due to mutation of p ATPase7 gene. Clinical manifestations include failure to thrive, mental retardation, seizures, and characteristic hypopigmented “kinky hair.” Menkes disease. Anthropometric measurement revealed weight 4.5 kg, length 63 cm, head circumference 40.5 cm, chest circumference 36.5 cm, there was mild pallor, skull, spines and bones were normal. The Menkes kinky hair disease (MD) is a rare progressive neuro- patient had one older sister aged 3 years who reportedly had degenerative disorder with abnormal expression or deletion of similar hair appearance. A Texas A&M AgriLife Research team has good news for patients with copper-deficiency disorders, especially young children diagnosed with Menkes disease.

The decreased supply of copper can reduce the activity of numerous copper-containing enzymes that are necessary for the structure and function of bone, skin, hair, blood vessels, and the nervous system. Females, who have two X chromosomes, may carry a defective copy of ATP7A on one but will not develop the disease if their second X chromosome is normal. This gene is responsible for production of the ATPase enzyme that regulates copper levels in the body. Individuals with Menkes disease have an abnormally low level of copper in the brain and liver and excess copper in the intestines and kidneys. 1999, 41 (4): 423-429. The clinical manifestations of Menkes disease are due to deficiency of copper-dependent enzymes that are involved in cellular respiration, antioxidant function, neurotransmitter synthesis, the structure and pigmentation of hair, collagen and elastin formation, and other processes. an X-linked genetic disorder caused by mutations in the ATP7A gene that is responsible for production of the ATPase enzyme that regulates copper levels in the body. EEG showed gross generalized polyspike waves. Pineal Night-Specific ATPase.

ATP7A encodes a transmembrane copper-transporting P-type ATPase, a molecule involved in copper efflux from cells. 11. Menkes disease; This section deals with the principles of lysosomal, peroxisomal, mitochondrial, and amino acid disorders, and highlights some important entities in these groups. Cases Journal 1, 158 (2008). Clinical and Translational Perspectives on Wilson Disease brings together the genetics, cell and structural biology of Wilson Disease into one contemporary, easy to navigate handbook. Microscopic examination of hair revealed classical sign of pili torti. Wilson is due to an inability to secrete copper into bile (copper is normally excreted through bile). AKD was responsible for patient care, follow up and drafting of paper, TNG collected data and assisted AKD to prepare manuscript, KN coordinated the study and MKG involved in he radiological investigation of the study. Menkes is a rare genetic disorder occurring in about 1 in every 50,000-300,000 births. Menkes disease patients display severe developmental, neurological and connective tissue abnormalities along with various other symptoms that are associated with a decreased function of copper-dependent enzymes (Lutsenko et al., 2007; Tomita et al., 1992). Treatment outcome depends on the severity of ATP7A gene deletion and residual functioning ATP7A protein. Menkes disease is an X-linked recessive disorder of copper metabolism. Menkes kinky hair disease: A case report. Site-specific cellular deficiencies of copper lead to loss of function of copper-dependent enzymes in all tissues, and the range of Menkes disease pathologies observed can now be explained in full by lack of specific copper enzymes. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Decreased activity of the copper-dependent enzyme cytochrome c oxidase is likely a major factor in the brain damage associated with Menkes disease. “These were difficult and time-consuming experiments that required special precautions because we were working with very sick mice, ones that carried the same type of mutation as humans with severe Menkes disease,” Guthrie said. In Menkes’ disease malabsorption of copper, increased renal losses, and aberrant distribution of copper within cells cause deficient activity of copper enzymes with important effects on brain, arterial walls, and other connective tissues as well as deficient pigmentation and abnormal hair. 2001, New York McGraw-Hill, 3105-3126. Asok K Datta. The disease usually manifests at the age of 2–3 month and usually die at 3–4 years of age due to pneumonia. This gene is responsible for the production of ATPase enzymes in the body that controls copper levels. 1998, 76: 154-164. Kirodian BG, Gogtay NJ, Udani VP, Kashirsagar NA: Treatment of Menkes disease with parental copper histidine. He had also mental retardation. The growth failure in our case is also a common finding of this syndrome. Catechol levels are abnormal in individuals with Menkes disease because dopamine-beta-hydroxylase is a copper-dependent enzyme involved in catecholamine biosynthesis. Serum copper and ceruloplasmin levels were low, MRI showed prominent extraaxial spaces with gliosis, MR angiography revealed tortuosity of cerebral vessels. HGNC:869. The aim of treatment is to bypass the normal route of absorption of copper through the gastrointestinal tract. 10.1046/j.1442-200x.1999.01095.x. It is caused by a mutation in the copper-transporting P-type ATPase (ATP7A) gene, which regulates copper's absorption from the intestines, its transport through the blood-brain and blood-cerebrospinal barriers and its movement from the cytosol to the cells' Golgi compartments, where it is … Menkes disease is an X-linked recessive copper deficiency disorder caused by mutations in the ATP7A (MNK) gene.
