The c.1436G>A (p.S479N) alteration is located in exon 8 (coding exon 8) of the PDZD4 gene. This alteration results from a G to A substitution at nucleotide position 1436, causing the serine (S) at amino acid position 479 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
