The c.1499G>A (p.G500D) alteration is located in exon 14 (coding exon 14) of the PYROXD2 gene. This alteration results from a G to A substitution at nucleotide position 1499, causing the glycine (G) at amino acid position 500 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
