The c.2275G>C (p.A759P) alteration is located in exon 5 (coding exon 5) of the PDZD8 gene. This alteration results from a G to C substitution at nucleotide position 2275, causing the alanine (A) at amino acid position 759 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
