Menkes disease is an inherited disorder in which the body has a problem absorbing copper. The disease affects development, both mental and physical.
Steely hair disease; Menkes kinky hair syndrome; Kinky hair disease; Copper transport disease; Trichopoliodystrophy; X-linked copper deficiency
Menkes disease is caused by a defect in the ATP7A gene. The defect makes it hard for the body to properly distribute (transport) copper throughout the body. As a result, the brain and other parts of the body do not get enough copper, while it builds up in the small intestine and kidneys. A low copper level can affect the structure of bone, skin, hair, and blood vessels, and interfere with nerve function.
Menkes syndrome is usually inherited, which means it runs in families. The gene is on the X-chromosome, so if a mother carries the defective gene, each of her sons has a 50% (1 in 2) chance of developing the disease, and 50% of her daughters will be a carrier of the disease. This kind of gene inheritance is called X-linked recessive.
In some people, the disease is not inherited. Instead, the gene defect occurs after birth.
Common symptoms of Menkes disease in infants are:
- Brittle, kinky, steely, sparse, or tangled hair
- Pudgy, rosy cheeks, sagging facial skin
- Feeding difficulties
- Lack of muscle tone, floppiness
- Low body temperature
- Intellectual disability and developmental delay
- Skeletal changes
Exams and Tests
Once Menkes disease is suspected, tests that may be done include:
- Ceruloplasmin blood test (substance that transports copper in the blood)
- Copper blood test
- Skin cell culture
- X-ray of the skeleton or x-ray of the skull
- Gene testing to check for defect of the ATP7A gene
Treatment usually only helps when started very early in the course of the disease. Injections of copper into a vein or under the skin have been used with mixed results and depends on whether the ATP7A gene still has some activity.

Most children with this disease die within the first few years of life.
When to Contact a Medical Professional
Talk to your health care provider if you have a family history of Menkes syndrome and you plan to have children. A baby with this condition will often show symptoms early in infancy.
See a genetic counselor if you want to have children and you have a family history of Menkes syndrome. Maternal relatives (relatives on the mother's side of the family) of a boy with this syndrome should be seen by a geneticist to find out if they are carriers.
