NCS + EMG lower limbs
In both lower limbs, there is a marked reduction in the conduction velocities of both sensory and motor nerves, with evidence of denervation of the distal muscles.
WBC: 3/mm3 (0 - 5)
Protein: 0.2 g/dl (0.15 - 0.4)
Glucose: 80 mg/dl
Random blood glucose: 100mg/dl
Sural nerve biopsy
The biopsy shows a mild loss of myelinated axons. Prominent onion bulb formations are evident upon both light microscopy and ultrastructural examination.
There is duplication of the peripheral myelin protein-22 (PMP22) gene on chromosome 17.
