The c.3377A>G (p.D1126G) alteration is located in exon 5 (coding exon 5) of the PDZD8 gene. This alteration results from a A to G substitution at nucleotide position 3377, causing the aspartic acid (D) at amino acid position 1126 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
