Genes affected
KIF1C (HGNC:6317): (kinesin family member 1C) The protein encoded by this gene is a member of the kinesin-like protein family. The family members are microtubule-dependent molecular motors that transport organelles within cells and move chromosomes during cell division. Mutations in this gene are a cause of spastic ataxia 2, autosomal recessive. [provided by RefSeq, May 2014]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.1780G>A (p.V594I) alteration is located in exon 20 (coding exon 18) of the KIF1C gene. This alteration results from a G to A substitution at nucleotide position 1780, causing the valine (V) at amino acid position 594 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
