The c.3026A>C (p.H1009P) alteration is located in exon 16 (coding exon 16) of the PSD3 gene. This alteration results from a A to C substitution at nucleotide position 3026, causing the histidine (H) at amino acid position 1009 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
