Menkes syndrome is an inherited genetic disorder due to an abnormal gene, ATP7A. Menkes syndrome causes impaired copper absorption. This results in changes in the arteries and deterioration of the brain.
Menkes syndrome is rare. Most children born with Menkes syndrome have a life expectancy of 3-5 years.
Copper proteins are necessary for the body to build bone, nerves, and other tissue. Babies with Menkes syndrome have a genetic disorder that prevents the absorption of copper from the intestines and causes it to build up in excess amounts in the kidney, while remaining deficient in the liver and brain. This causes changes in the hair, brain, bones, liver, and arteries.
Menkes syndrome is more common in males, and in those with a family history.
Children with Menkes are often born prematurely. Symptoms usually begin within 3 months after birth and may include:
- Difficulty feeding
- Developmental delays
- Floppy muscle tone

Babies with Menkes syndrome often exhibit the following physical characteristics:
- Hair that is stubby, tangled, sparse, lacking in color, and easily broken
- Chubby, rosy
- Flattened bridge of the nose
- Face lacking in expression
The following tests may be done to diagnose Menkes syndrome:
of the skull and skeleton to look for abnormalities in bone formation
- Blood tests to measure copper levels
There is no cure for Menkes syndrome. Early treatment with IV copper acetate, oral copper supplements, or injections of copper histidinate may provide temporary benefit. Other treatments may be used to relieve symptoms.
There is no known way to prevent Menkes syndrome. If you have a family history of the disorder, you can talk to a genetic counselor when deciding whether to have children.
