Charcot-Marie-Tooth disease type 4K
MONDO:0014733SURF1-related Charcot-Marie-Tooth disease type 4 (CMT4K) is a subtype of Charcot-Marie-Tooth disease type 4 characterized by childhood onset of severe, progressive, demyelinating sensorimotor neuropathy manifesting with distal muscle weakness and atrophy of hands and feet, distal sensory impairment (vibration and pinprick) of lower limbs, lactic acidosis, areflexia and severely reduced motor nerve conduction velocities (25 m/s or less). Patients may also present kyphoscoliosis, nystagmus, hearing loss, cerebellar ataxia and/or brain MRI abnormalities (putaminal and periaqueductal lesions).
Also known as: CMT4K, Charcot-Marie-Tooth disease type 4 caused by mutation in SURF1, Charcot-Marie-Tooth disease type 4K, Charcot-Marie-Tooth disease, type 4k, SURF1 Charcot-Marie-Tooth disease type 4, SURF1-related CMT4, SURF1-related Charcot-Marie-Tooth disease type 4, SURF1-related severe demyelinating Charcot-Marie-Tooth disease

Could a simple blood test track nerve damage? a study investigates NT-3 levels in neuropathy.
Knowledge-focused Stopped earlyThis study measures levels of a protein called NT-3 in the blood of people with peripheral neuropathy or Charcot-Marie-Tooth disease. Researchers will compare these levels with measures of muscle strength, mobility, and daily function. The goal is to see whether NT-3 levels corre…
