Genes affected

KIF23 (HGNC:6392): (kinesin family member 23) The protein encoded by this gene is a member of kinesin-like protein family. This family includes microtubule-dependent molecular motors that transport organelles within cells and move chromosomes during cell division. This protein has been shown to cross-bridge antiparallel microtubules and drive microtubule movement in vitro. Alternate splicing of this gene results in multiple transcript variants.

The c.121G>A (p.E41K) alteration is located in exon 3 (coding exon 3) of the KIF23 gene. This alteration results from a G to A substitution at nucleotide position 121, causing the glutamic acid (E) at amino acid position 41 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
