Menkes Disease

Menkes disease is caused by a defective gene named ATPTA1 that regulates the metabolism of copper in the body. The disease primarily affects male infants. Copper accumulates at abnormally low levels in the liver and brain, but at higher than normal levels in the kidney and intestinal lining. Affected infants may be born prematurely, but appear healthy at birth and develop normally for 6 to 8 weeks. Then symptoms begin, including floppy muscle tone, seizures, and failure to thrive.  Menkes disease is also characterized by subnormal body temperature and strikingly peculiar hair, which is kinky, colorless or steel-colored, and breaks easily. There is often extensive neurodegeneration in the gray matter of the brain. Arteries in the brain may be twisted with frayed and split inner walls. This can lead to rupture or blockage of the arteries. Weakened bones (osteoporosis) may result in fractures.

Treatment

Treatment with daily copper injections may improve the outcome in Menkes disease if it begins within days after birth.  Other treatment is symptomatic and supportive.

Prognosis

Since newborn screening for this disorder is not available, and early detection is infrequent because the clinical signs of Menkes disease are subtle in the beginning, the disease is rarely treated early enough to make a significant difference.  The prognosis for babies with Menkes disease is poor. Most children with Menkes disease die within the first decade of life.

Research

Recent research sponsored by the NINDS developed a blood test that could be given to newborns at risk for Menkes disease based on a positive family history for the disorder or other indications.  The test measures 4 different chemicals in the blood and, depending upon their levels, can accurately diagnose the presence of Menkes disease before symptoms appear.  Study results showed higher survival rates for children given the earliest copper injection treatment and improved, if not normal, 2.  Additional research is being performed by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, in collaboration with the NINDS, that applies gene therapy approaches to Menkes disease.3 1.  Kaler, SG.
