Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 1P and 3B. PP2BP4BP6_Moderate

The NM_001244008.2(KIF1A):c.3286C>T(p.Arg1096Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000577 in 1,612,778 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. R1096R) has been classified as Benign.

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 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.37083215).

BP6

Variant 2-240745826-G-A is Benign according to our data. Variant chr2-240745826-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 532860.Status of the report is criteria_provided_single_submitter, 1 stars.
