What is giant axonal neuropathy?
Giant axonal neuropathy (GAN) is a rare inherited disorder that affects the peripheral and central nervous system. The peripheral nervous system sends signals that control movement and sensation between the central nervous system (the brain and spinal cord) and all other parts of the body. GAN happens when the GAN1 gene is changed and causes the axons, or the message sender of the nerve cell, to become larger than normal and not function properly. After some time, these axons will break down and affect movement and feeling because the nerve cells can't talk to each other.
GAN is progressive, meaning that is continues to worsen over time. Most children will begin showing signs of GAN before five years of age. Most children will need to use a wheelchair in the second decade of life, and some may survive into early adulthood. Currently there is no cure or treatment to stop the disorder from progressing.

How can I or my loved one help improve care for people with giant axonal neuropathy?
Consider participating in a clinical trial so clinicians and scientists can learn more about GAN and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.
All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.
