The c.782A>G (p.E261G) alteration is located in exon 9 (coding exon 9) of the PDXDC1 gene. This alteration results from a A to G substitution at nucleotide position 782, causing the glutamic acid (E) at amino acid position 261 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
