Giant Axonal Neuropathy: A Rare Neurological Disorder with Compassionate Allowance

Written By Jacky Writes

Giant Axonal Neuropathy (GAN) is a rare, inherited neurological disorder that primarily affects the peripheral nervous system and central nervous system. People living with GAN often face severe physical challenges as the disease progressively worsens.

Giant Axonal Neuropathy is listed in the Social Security Administration’s (SSA) Compassionate Allowances List, which means that individuals diagnosed with GAN may have their disability cases processed more quickly, allowing them to receive benefits sooner​.

What Causes Giant Axonal Neuropathy?

GAN is caused by mutations in the GAN gene, which affects the production of gigaxonin, a protein essential for maintaining healthy axons (the long fibers that conduct nerve signals). Without proper gigaxonin function, axons accumulate abnormal proteins, which leads to nerve damage and loss of function over time.

Understanding Giant Axonal Neuropathy in Simple Terms

Think of the axons in your nerves like electrical wires, with the GAN gene serving as the insulation that keeps the wires healthy and functional. In GAN, this insulation (gigaxonin) is defective, causing the wires to short circuit, leading to neurological symptoms.

Effects on Daily Life

Giant Axonal Neuropathy begins to show symptoms in early childhood and worsens over time. It typically results in a variety of physical and cognitive impairments, such as difficulty walking, muscle weakness, and coordination issues. As the disease progresses, individuals may become wheelchair-dependent, and the cognitive decline can affect memory and problem-solving skills. These effects severely limit the ability to work, participate in daily activities, and attend school, leading to significant challenges in maintaining independence.

Treatment and Research Advances

Currently, there is no cure for GAN, and treatment is focused on managing symptoms and improving quality of life. Physical therapy, occupational therapy, and supportive devices like braces or wheelchairs can help alleviate some of the physical difficulties associated with the disease.

Optimistic research is underway, including gene therapy trials, which aim to replace the defective GAN gene with a healthy version. Preliminary results have shown promise, offering hope for a treatment that might slow or even reverse some of the disease’s effects. Ongoing studies in gene editing and neuroprotective treatments are advancing our understanding of this rare condition.

Giant Axonal Neuropathy and SSDI

The Social Security Disability Insurance (SSDI) program recognizes Giant Axonal Neuropathy under its Compassionate Allowances List, meaning that individuals can apply for benefits and potentially receive faster processing for their claim​. To start a disability claim for GAN, it is important to demonstrate how the disease limits both physical and mental function, as per the SSA’s Blue Book guidelines. GAN significantly impacts neurological and motor skills, meeting the criteria for neurological disorders listed under section 11.17 (Neurological Disorders) in the SSA Blue Book. GAN is also classified as DI 23022.181 in the SSA Program Operations Manual System (POMS).

Summary

Giant Axonal Neuropathy is a progressive, rare genetic disorder that causes debilitating effects on the nervous system. While there is no current cure, advancements in gene therapy offer hope. For individuals diagnosed with GAN, Social Security Disability benefits are available, with expedited processing due to the disease’s inclusion on the Compassionate Allowances List.
