Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP2PP3

The ENST00000455537.7(KIF5A):​c.23G>T​(p.Cys8Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,852 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C8R) has been classified as Uncertain significance.

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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

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, 0.765

Submissions by phenotype

KIF5A-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesAug 03, 2023The KIF5A c.23G>T variant is predicted to result in the amino acid substitution p.Cys8Phe. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
