Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_004521.3(KIF5B):​c.1726-5T>G variant causes a splice region, splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

KIF5B (HGNC:6324): (kinesin family member 5B) Enables identical protein binding activity; microtubule binding activity; and microtubule motor activity. Involved in several processes, including lysosome localization; natural killer cell mediated cytotoxicity; and positive regulation of protein localization to plasma membrane. Located in centriolar satellite; cytosol; and vesicle. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
