About Menkes Disease

• It is a genetic disorder that affects your body’s ability to process copper.  
• It is caused by a mutation of the ATP7A gene located on the X chromosome. This ATP7A gene affects how the body transports copper and maintains copper levels.
  • While the body only uses a small amount of copper, even this tiny amount is required for many functions. 
  • Copper helps with metabolism, brain functioning, blood vessel and blood cell formation, wound healing, and the immune system. 
  • Copper also helps to convert iron into a usable form in the body.
  • It is naturally available in many foods and dietary supplements.
• Menkes Disease usually causes low copper levels in blood plasma, the liver, and the brain. 
• The condition also reduces the activities of copper-dependent enzymes in the body.
• Copper may accumulate in other tissues, such as the kidney. 
• Because the condition prevents the body from using copper correctly, Menkes disease can lead to serious damage to the brain and nervous system and can harm a child’s development.
• It occurs mostly in male infants and is characterized by coarse, kinky hair (leading to its nickname of “kinky hair disease”), as well as failure to grow and thrive. 
• It is believed to occur in about 1 in 35,000 live male births.
• Symptoms: Symptoms include seizures, slow growth, floppy muscles, and kinky (crinkly) hair. 
• Treatment: 
  • There isn’t a cure for Menkes disease, but early treatment with copper can help reduce symptoms and prolong life.
  • Treatment includes copper replacement injections (also known as a copper histidine compound) to increase the development of copper in your child’s body.
  • Without treatment, most Menkes disease patients do not survive past age 3.
