Genes affected

KIF2C (HGNC:6393): (kinesin family member 2C) This gene encodes a kinesin-like protein that functions as a microtubule-dependent molecular motor. The encoded protein can depolymerize microtubules at the plus end, thereby promoting mitotic chromosome segregation. Alternative splicing results in multiple transcript variants.

The c.1120T>A (p.Y374N) alteration is located in exon 12 (coding exon 12) of the KIF2C gene. This alteration results from a T to A substitution at nucleotide position 1120, causing the tyrosine (Y) at amino acid position 374 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
