A 3 2/12-year-old boy had recurrent seizures, chronic respiratory infection, and delayed physical and mental development. He also had low plasma copper content typical of Menkes syndrome. Autopsy showed marked neuronal loss and gliosis in most areas of the cerebral and cerebellar cortices, midbrain, pons, and medulla. The spinal cord showed severe demyelination in both ascending (spinocerebellar) and descending (lateral corticospinal) tracts from the cervical to the sacral level. In addition to these neuronal lesions, both the meningeal and parenchymal arterial and venous branches were remarkably dilated in the brain and spinal cord. Our previous study of this case showed abnormal perivascular innervation and abnormal axonal swelling of the postganglionic adrenergic fibers elsewhere in the body. The metabolic disorder caused by copper deficiency induces severe neuronal degeneration that is apparently exaggerated by extensive and progressive vascular abnormality.

Menkes disease is an infantile-onset X-linked recessive neurodegenerative disorder caused by diverse mutations in a copper-transport gene, ATP7A. Affected patients are characterized by progressive hypotonia, seizures, failure to thrive and death in early childhood. Here, we report a case of Menkes disease presented by intractable seizures and infantile spasms. A 3-month-old male infant had visited our pediatric clinic for lethargy, floppy muscle tone, poor oral intake and partial seizures. His hair was kinky, brown colored and fragile. Partial seizures became more frequent, generalized and intractable to antiseizure medications. An EEG showed frequent posteriorly dominant generalized spikes that were consistent with a generalized seizure. From a genetic analysis, a c.2743C>T (p.Gln915X) mutation was detected and diagnosed as Menkes disease. The mutation is a novel one that has not been previously reported as a cause of Menkes disease.
