Collection Method:clinical testing

The c.3389A>G (p.E1130G) 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 3389, causing the glutamic acid (E) at amino acid position 1130 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
