The c.50A>G (p.E17G) alteration is located in exon 1 (coding exon 1) of the PDZRN4 gene. This alteration results from a A to G substitution at nucleotide position 50, causing the glutamic acid (E) at amino acid position 17 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
