The c.1306G>C (p.E436Q) alteration is located in exon 8 (coding exon 8) of the PDZD4 gene. This alteration results from a G to C substitution at nucleotide position 1306, causing the glutamic acid (E) at amino acid position 436 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
