Popis: Background: KIF1C (Kinesin Family Member 1C) variants have been associated with hereditary spastic paraplegia and spastic ataxia. Case report: We report fraternal twins presenting with cerebellar ataxia and dystonic tremor. Their brain MRI showed a hypomyelinating leukoencephalopathy. Whole exome sequencing identified a homozygous KIF1C variant in both patients. Discussion: KIF1C variants can manifest as a complex movement disorder with cerebellar ataxia and dystonic tremor. KIF1C variants may also cause a hypomyelinating leukoencephalopathy.
