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 Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the KIF1A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 112 curated pathogenic missense variants (we use a threshold of 10). The gene has 150 curated benign missense variants. Gene score misZ: 5.1579 (above the threshold of 3.09). Trascript score misZ: 5.0191 (above the threshold of 3.09). GenCC associations: The gene is linked to 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.
