The c.515G>A (p.S172N) alteration is located in exon 3 (coding exon 3) of the PDZD9 gene. This alteration results from a G to A substitution at nucleotide position 515, causing the serine (S) at amino acid position 172 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
