The c.2168T>C (p.V723A) alteration is located in exon 19 (coding exon 19) of the KIF5B gene. This alteration results from a T to C substitution at nucleotide position 2168, causing the valine (V) at amino acid position 723 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
