Green List (high evidence)

Neonatal intractable myoclonus is a severe neurologic disorder characterized by the onset of intractable myoclonic seizures soon after birth. Affected infants have intermittent apnea, abnormal eye movements, pallor of the optic nerve, and lack of developmental progress. Brain imaging shows a progressive leukoencephalopathy. At least 3 unrelated individuals with de novo LoF variants.

SPG10/CMT: variants are generally in the motor domain.

Mutations in the KIF5A are associated with a wide phenotypic spectrum from hereditary spastic paraplegia (HSP) to axonal Charcot-Marie-Tooth peripheral neuropathy type 2 (CMT2).

Multiple families reported with neuropathy alone as well as HSP in association with neuropathy.
