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]

KIF1C-AS1 (HGNC:40324): (KIF1C antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.41).
• BP6: Variant 17-5022379-C-T is Benign according to our data. Variant chr17-5022379-C-T is described in ClinVar as Benign. ClinVar VariationId is 387794.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.196 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.111 is higher than 0.05.
