The c.965C>T (p.P322L) alteration is located in exon 7 (coding exon 7) of the KIFC1 gene. This alteration results from a C to T substitution at nucleotide position 965, causing the proline (P) at amino acid position 322 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
