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.

KIF2C (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.22217637).

The c.307C>T (p.P103S) alteration is located in exon 4 (coding exon 4) of the KIF2C gene. This alteration results from a C to T substitution at nucleotide position 307, causing the proline (P) at amino acid position 103 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
