The Charcot–Marie–Tooth Association classifies the chemotherapy drug vincristine as a "definite high risk" and states, "vincristine has been proven hazardous and should be avoided by all CMT patients, including those with no symptoms." Several corrective surgical procedures  can be done to improve the physical condition of the affected individuals. Orthotics
If the muscles of the lower extremities are weak, it makes sense to prescribe custom-fabricated orthotics. Depending on which muscle groups are affected, the correct orthoses with appropriate functional elements should be prescribed. A weakness of the Musculus tibialis anterior, which lifts the feet, is usually accompanied by an atrophy of the Musculus gastrocnemius which, together with the Musculus soleus, forms the Musculus triceps surae (distal calf muscles), occurs causing the known "stork leg deformity". In most cases, ankle-foot orthoses that have functional elements for the foot lifting and adjustable control of the lowering of the forefoot make sense. Weak calf muscles lead to insufficient activation of the forefoot lever. This leads to an additional increasing uncertainty when standing and walking. If the calf muscles are weak, an orthosis should therefore be equipped with functional elements to activate the forefoot lever. An orthotic joint with an adjustable dynamic dorsiflexion stop with strong spring in combination with a lower leg shell in front of the shin is recommended for this. Such orthoses help to control foot drop, instability of the foot and ankle and offer the patient a better sense of balance when standing and walking without restricting mobility and the dynamics of the ankle joint.
Symptoms of CMT2D include foot deformity, muscle weakness and cramping, compromised reflexes, loss of sensation, and muscle atrophy and are similar to the symptoms of other both CMT1 and CMT2 types. Symptoms and severity vary from patient to patient.Mice are often used to model CMT2D and typically demonstrate aberrant neuromuscular function at the neuromuscular junction (NMJ). The neuromuscular junction is abnormal in CMT2D mice, with subjects showing neuromuscular junction degeneration in hind muscles. The dorsal root ganglia (DRG) is also affected via aberrant sensory neuron fate, meaning that sensory neuron cell fates are abnormally determined. CMT2D mice have fewer proprioceptive and mechanosensitive neurons, but have more nociceptive neurons, possibly due to mutant GlyRS aberrantly interacting with the extracellular region of tropomyosin receptor kinase, or Trk, receptors. Trk receptors are crucial to the survival and development of sensory neurons; when disrupted, nerve development and survival is disrupted as well, possibly leading to the abnormal sensory neuron counts observed in CMT2D mice.CMT2D is a result of autosomal dominant mutations in the human GARS1 gene located at 7p14.3  and is thought to be caused by aberrant gain-of-function missense mutations. The GARS1 gene is a protein-coding gene responsible for the encoding of glycyl-tRNA synthetase (GlyRS). Glycyl-tRNA synthetase is a class II aminoacyl-tRNA synthetase and acts as the catalyst for the synthesis of glycyl-tRNA by covalently bonding amino acids with their corresponding cognate tRNAs for protein translation.
