Giant axonal neuropathy is a rare, autosomal recessive neurological disorder that causes disorganization of neurofilaments. Neurofilaments form a structural framework that helps to define the shape and size of neurons and are essential for normal nerve function.iant axonal neuropathy has an autosomal recessive pattern of inheritance. Giant axonal neuropathy results from mutations in the GAN gene, which codes for the protein gigaxonin. This alters the shape of the protein, changing how it interacts with other proteins when organizing the structure of the neuron.
Neuropathy is when nerve damage interferes with the peripheral nervous systemâs (PNSâs) ability to function. When no cause can be determined, it is called idiopathic neuropathy. The PNS carries information from the central nervous system (CNS), or brain and spinal cord, to the rest of the body. Within the PNS are three kinds of nerves. Sensory nerves relay messages from the senses to the brain.
