The c.625C>G (p.R209G) alteration is located in exon 4 (coding exon 4) of the PXMP4 gene. This alteration results from a C to G substitution at nucleotide position 625, causing the arginine (R) at amino acid position 209 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
