Genes affected
KIF1A (HGNC:888): (kinesin family member 1A) The protein encoded by this gene is a member of the kinesin family and functions as an anterograde motor protein that transports membranous organelles along axonal microtubules. Mutations at this locus have been associated with spastic paraplegia-30 and hereditary sensory neuropathy IIC. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Apr 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KIF1A. . Gene score misZ 5.1579 (greater than the threshold 3.09). Trascript score misZ 5.0191 (greater than threshold 3.09). GenCC has associacion of gene with neuropathy, hereditary sensory, type 2C, hereditary spastic paraplegia 30, syndromic intellectual disability, intellectual disability, autosomal dominant 9, PEHO syndrome, autosomal dominant non-syndromic intellectual disability, hereditary sensory and autonomic neuropathy type 2.
BP4
Computational evidence support a benign effect (MetaRNN=0.14887133).
BP6
Variant 2-240742970-G-A is Benign according to our data. Variant chr2-240742970-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 464229.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}. Variant chr2-240742970-G-A is described in Lovd as [Likely_benign].
