Deficient activity of the\n                    <jats:italic>ATP7A<\/jats:italic>\n                    protein results in decreased intestinal absorption of copper, low copper level in serum and defective distribution of copper in tissues. The clinical symptoms are caused by decreased activities of copper-dependent enzymes and include neurodegeneration, connective tissue disorders, arterial changes and hair abnormalities. Without therapy, the disease is fatal in early infancy. Rapid diagnosis of Menkes disease and early start of copper therapy is critical for the effectiveness of treatment. We report a molecular biology-based strategy that allows early diagnosis of copper transport defects and implementation of individual therapies before the full development of pathological symptoms. Low serum copper and decreased activity of copperdependent mitochondrial cytochrome c oxidase in isolated platelets found in three patients indicated a possibility of functional defects in copper-transporting proteins, especially in the ATPA7 protein, a copper-transporting P-type ATPase. Rapid mutational screening of the\n                    <jats:italic>ATP7A<\/jats:italic>\n                    gene using high-resolution melting analysis of DNA indicated presence of mutations in the patients. Molecular investigation for mutations in the ATP7A gene revealed three nonsense mutations: c.2170C&gt;T (p.Gln724Ter); c.3745G&gt;T (p.Glu1249Ter); and c.3862C&gt;T (p.Gln1288Ter). The mutation c.3745G&gt;T (p.Glu1249Ter) has not been identified previously. Molecular analysis of the\n                    <jats:italic>ATOX1<\/jats:italic>\n                    gene as a possible modulating factor of Menkes disease did not reveal presence of pathogenic mutations. Molecular diagnostics allowed early onset of individual therapies, adequate genetic counselling and prenatal diagnosis in the affected families.\n                  <\/jats:p>","DOI":"10.14712\/fb2017063050165","type":"journal-article","created":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T14:15:53Z","timestamp":1709302553000},"page":"165-173","source":"Crossref","is-referenced-by-count":2,"title":["Molecular Diagnostics of Copper-Transporting Protein Mutations Allows Early Onset Individual Therapy of Menkes Disease"],"prefix":"10.14712","volume":"63","author":[{"given":"L.","family":"Kr\u00e1l\u00edk","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Flachsov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Hans\u00edkov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Saudek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Zeman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Mart\u00e1sek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5727","published-online":{"date-parts":[[2024,3,1]]},"reference":[{"key":"fb2017063050165_1","doi-asserted-by":"crossref","first-page":"1219","DOI":"10.1016\/j.str.2011.05.014","volume":"19","author":"Allen","year":"2011","journal-title":"Structure"},{"key":"fb2017063050165_2","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1038\/nsmb.2721","volume":"21","author":"Andersson","year":"2014","journal-title":"Nat.
