Added comment: 24 individuals from 12 families reported with severe, acute-onset axonal neuropathy following infection (13 female and 11 male patients, with a mean age at diagnosis of 1 year 10 months [SD 2·27]).

Eight biallelic missense variants in RCC1 identified.

Patients had variable phenotypes, ranging from rapidly progressive fatal axonal neuropathy to mild motor neuropathy with impaired walking. Neurological presentation was often secondary to an infection, resulting in initial misdiagnoses of Guillain-Barré syndrome in several patients. 15 children had disease recurrence. The disease was fatal in 15 patients.

The RCC1 variants coded for proteins that alter GDP-to-GTP exchange activity and had reduced thermal stability in vitro. In primary fibroblasts, heat shock or oxidative stress revealed defects in Ran nuclear localisation and impaired nucleocytoplasmic transport. A Drosophila model of the disease revealed a fatal intolerance to oxidative stress.
