OBSOLETE: X-linked recessive hereditary axonal motor and sensory neuropathy

X-linked recessive hereditary axonal motor and sensory neuropathy is a form of Charcot-Marie-Tooth disease (CMT) that affects the peripheral nerves — the nerves that connect the brain and spinal cord to the muscles and sensory organs in the arms and legs. This condition is classified as 'obsolete' in current medical databases, meaning it has been reclassified or merged into other recognized forms of X-linked CMT (such as CMTX). The term 'axonal' refers to damage primarily affecting the axons, which are the long fibers of nerve cells that carry electrical signals. Because it follows an X-linked recessive inheritance pattern, it mainly affects males, while females may be carriers with milder or no symptoms. Patients with this type of neuropathy typically experience progressive muscle weakness and wasting, especially in the feet, lower legs, hands, and forearms. Sensory problems such as numbness, tingling, or reduced ability to feel pain and temperature changes are also common. Symptoms usually begin in childhood or adolescence and worsen slowly over time. Foot deformities like high arches (pes cavus) and hammertoes may develop. Walking difficulties and balance problems are frequent. There is currently no cure for this condition. Treatment focuses on managing symptoms and maintaining function. Physical therapy, occupational therapy, orthotic devices (such as braces or special shoes), and sometimes surgery for foot deformities are the main approaches. Pain management may also be needed. Research into gene therapies and other disease-modifying treatments for CMT is ongoing but not yet available as standard care.
