The c.1921G>C (p.E641Q) alteration is located in exon 5 (coding exon 5) of the KIF3C gene. This alteration results from a G to C substitution at nucleotide position 1921, causing the glutamic acid (E) at amino acid position 641 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
