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.
Digging Deeper. Because there are different types of neuropathy, patients may exhibit a wide variation in symptoms. Wolfe says most neuropathies are axonal, which generally requires more diagnostic evaluation to determine the cause. Deciding which tests are appropriate depends on the suspected cause.
