| Definition: |
An inherited disorder that results in problems in multiple parts of the body due to cells not having enough copper.
|
| Alternative Names: |
Steely hair disease; Menkes kinky hair syndrome; Kinky hair disease
|
| Causes, incidence, and risk factors: |
| Menkes syndrome is inherited as an X-linked recessive disorder. The disorder is related to deficient levels of copper availability to cells. Symptoms include progressive mental deterioration, kinked, twisted and brittle hair, as well as skeletal changes. Death usually occurs in the first few years of life. About 1 in 300,000 individuals are affected. |
| Signs and tests: |
There is often a history of Menkes syndrome in a male relative. Signs include slow growth in the womb, abnormally low body temperature, bleeding in the brain and abnormal appearance of the hair under the microscope. Males will have 100% of their hairs show abnormal structure but carrier-females may show only half the hairs to be abnormal.
Tests:
- X-ray of the skeleton or X-ray of the skull may show abnormal bone appearance (Wormian bones and metaphyseal widening)
- serum copper level may be low
- copper level in cultured skin cells (fibroblasts) is up to 5 times elevated
- serum ceruloplasmin level may be low
- microscope examination of the hair may show breaks at regular intervals
- plasma amino acids may show elevated glutamate
- genetic testing may show mutation in the ATP7A gene
|
| Treatment: |
Injection of copper has been used with mixed results. Present therapy consists of:
- copper acetate administered into a vein (intravenously)
- subcutaneous (injected under the skin) copper histidinate

| Expectations (prognosis): |
| Menkes is a serious disorder with early death being common. |
| Complications: |
| Seizures, abnormally light pigmentation of the skin and hair. Death usually occurs in the first few years of life. |
| Calling your health care provider: |
| Consult with 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. |
| Prevention: |
| Genetic counseling is recommended for prospective parents with a family history of Menkes syndrome. Evaluation by a geneticist is recommended for maternal relatives of an affected boy to determine genetic risks and carrier status. |
