Genes affected

KIF20B (HGNC:7212): (kinesin family member 20B) Enables several functions, including WW domain binding activity; plus-end-directed microtubule motor activity; and protein homodimerization activity. Involved in positive regulation of cell population proliferation and positive regulation of cytokinesis. Located in several cellular components, including microtubule cytoskeleton; midbody; and nuclear lumen. [provided by Alliance of Genome Resources, Apr 2022]

The c.374A>G (p.Q125R) alteration is located in exon 5 (coding exon 4) of the KIF20B gene. This alteration results from a A to G substitution at nucleotide position 374, causing the glutamine (Q) at amino acid position 125 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
