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.397A>G (p.I133V) 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 397, causing the isoleucine (I) at amino acid position 133 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
