The c.977A>C (p.Q326P) alteration is located in exon 7 (coding exon 7) of the KIAA1328 gene. This alteration results from a A to C substitution at nucleotide position 977, causing the glutamine (Q) at amino acid position 326 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
