Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP2 PP3_Strong

The NM_004984.4(KIF5A):​c.610C>G​(p.Arg204Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R204Q) has been classified as Likely pathogenic.

• Frequency: Genomes: not found (cov: 28)
• Consequence: KIF5A NM_004984.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.568

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 Pathogenic. Variant got 11 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
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr12-57567515-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 37129.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KIF5A. . Gene score misZ 3.5984 (greater than the threshold 3.09). Trascript score misZ 5.0239 (greater than threshold 3.09). GenCC has associacion of gene with amyotrophic lateral sclerosis, susceptibility to, 25, inherited neurodegenerative disorder, hereditary spastic paraplegia 10, myoclonus, intractable, neonatal, autosomal dominant Charcot-Marie-Tooth disease type 2 due to KIF5A mutation.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.98
