Genes affected

KIF1B (HGNC:16636): (kinesin family member 1B) Predicted to enable microtubule binding activity and plus-end-directed microtubule motor activity. Predicted to be involved in chemical synaptic transmission; dense core granule cytoskeletal transport; and vesicle-mediated transport. Predicted to act upstream of or within mitochondrion transport along microtubule. Predicted to be located in cytoplasmic vesicle membrane and neuron projection. Predicted to be part of kinesin complex. Predicted to be active in several cellular components, including axon; dendrite; and microtubule. Implicated in Charcot-Marie-Tooth disease type 2A1; carcinoma (multiple); multiple sclerosis; neuroblastoma; and pheochromocytoma. Biomarker of hepatocellular carcinoma.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -21 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.67).

BP6

Variant 1-10361031-G-A is Benign according to our data. Variant chr1-10361031-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 284219.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-3.96 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.000481 (702/1458548) while in subpopulation AFR AF = 0.0169 (564/33402). AF 95% confidence interval is 0.0157. There are 3 homozygotes in GnomAdExome4. There are 289 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
