Abstract
We analyzed a sural nerve biopsy of a child with congenital hypomyelinating neuropathy.
A lack of normally myelinated fibres, abnormal architecture of premyelin fibres and
basal lamina onion bulbs were identified. The most prominent pathological finding
was the appearance of significant death of Schwann cells with apoptotic morphology.
This new finding may suggest that abnormal premyelin fibres are susceptible to death
and that their disappearance is responsible for empty basal lamina onion bulb formation.
