Collection Method: clinical testing

The c.3015G>T (p.E1005D) alteration is located in exon 5 (coding exon 5) of the PDZD8 gene. This alteration results from a G to T substitution at nucleotide position 3015, causing the glutamic acid (E) at amino acid position 1005 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
