Dec 28, 2022

The c.728G>T (p.G243V) alteration is located in exon 6 (coding exon 6) of the KIFC1 gene. This alteration results from a G to T substitution at nucleotide position 728, causing the glycine (G) at amino acid position 243 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
