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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.01151219).

BP6

Variant 17-5004946-G-A is Benign according to our data. Variant chr17-5004946-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 424675.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=4}.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00355 (541/152368) while in subpopulation NFE AF = 0.00525 (357/68040). AF 95% confidence interval is 0.0048. There are 1 homozygotes in GnomAd4. There are 268 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position FAILED quality control check.

BS2
