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
• 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, 0.973
• PP5: Variant 12-57569015-A-G is Pathogenic according to our data. Variant chr12-57569015-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 6806.Status of the report is criteria_provided_single_submitter, 1 stars.
