The c.1364A>T (p.E455V) alteration is located in exon 10 (coding exon 10) of the KIF3A gene. This alteration results from a A to T substitution at nucleotide position 1364, causing the glutamic acid (E) at amino acid position 455 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
