The c.714G>T (p.E238D) alteration is located in exon 8 (coding exon 8) of the PYROXD2 gene. This alteration results from a G to T substitution at nucleotide position 714, causing the glutamic acid (E) at amino acid position 238 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
