What Is Childhood Giant Axonal Neuropathy?

Childhood Giant Axonal Neuropathy (GAN) is a rare and debilitating genetic disorder that affects the peripheral nervous system. It is characterized by the degeneration of the axons, which are the long, slender extensions of nerve cells that transmit signals between the brain and the rest of the body.

What Happens in Childhood GAN?

In Childhood GAN, the axons of the peripheral nerves become abnormally enlarged, leading to a disruption in the transmission of nerve signals. This can cause a range of symptoms, including muscle weakness, numbness, and tingling sensations in the hands and feet. As the disease progresses, it can lead to muscle atrophy, loss of reflexes, and difficulty with balance and coordination.

Childhood GAN is usually diagnosed in early childhood, typically between the ages of 2 and 10. It is a progressive disease, meaning that it will worsen over time if left untreated.

Causes and Risk Factors of Childhood Giant Axonal Neuropathy

Childhood GAN is caused by mutations in the GAN gene, which codes for the protein gigaxonin. This protein plays a crucial role in the maintenance of axonal structure and function. Mutations in the GAN gene lead to the abnormal enlargement of axons, disrupting nerve function and leading to the symptoms of Childhood GAN.

Genetic Inheritance

Childhood GAN is an autosomal recessive disorder, meaning that a child must inherit two copies of the mutated GAN gene (one from each parent) to develop the condition. If a child inherits only one mutated gene, they will be a carrier of the condition but will not develop symptoms themselves.

Parents who are carriers of the mutated GAN gene have a 25% chance of passing it on to each child. If you have a family history of Childhood GAN, it is essential to consult with a genetic counselor to understand the risks and options for genetic testing.

While there is currently no cure for Childhood GAN, researchers are working to develop new treatments and therapies to manage the condition. If you or a loved one has been diagnosed with Childhood GAN, it is essential to work with a healthcare team to develop a personalized treatment plan.
