Genes affected

KIF5A (HGNC:6323): (kinesin family member 5A) This gene encodes a member of the kinesin family of proteins. Members of this family are part of a multisubunit complex that functions as a microtubule motor in intracellular organelle transport. Mutations in this gene cause autosomal dominant spastic paraplegia 10. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_004984.4
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, KIF5A
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.927
• PP5: Variant 12-57569304-G-C is Pathogenic according to our data. Variant chr12-57569304-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 424659.Status of the report is criteria_provided_single_submitter, 1 stars.
