A rare genetic autosomal recessive axonal hereditary motor and sensory neuropathy disease with characteristics of prenatal onset of a severe sensorimotor axonal polyneuropathy reflected by reduced fetal movement and polyhydramnios. The disease manifests at birth with respiratory failure requiring mechanical ventilation, profound muscular hypotonia, rapidly progressing distal muscle weakness and absent deep tendon reflexes in the absence of contractures leading to death before 8 months of age. Neuropathological findings show severe loss of large and medium sized myelinated fibres without signs of demyelination. [from SNOMEDCT_US]
