Types of Giant axonal neuropathy
There are two types of Giant axonal neuropathy (GAN), Type I and Type II. In Type I GAN, symptoms typically appear in early childhood and progress slowly. This type of GAN is caused by mutations in the GAN gene, leading to nerve cells not functioning properly and the accumulation of abnormal structures called giant axons. Symptoms include weak muscles, difficulty walking, and loss of sensation in the hands and feet.
On the other hand, Type II GAN is a more severe form of the condition, with symptoms appearing in early infancy and progressing rapidly. This type is also caused by mutations in the GAN gene, resulting in similar nerve cell dysfunction and giant axon formation. In addition to the symptoms seen in Type I GAN, individuals with Type II may also experience respiratory problems, seizures, and developmental delays. Managing both types of GAN involves supportive care to address symptoms and improve quality of life.
