The c.950G>A (p.G317D) alteration is located in exon 9 (coding exon 8) of the FAXDC2 gene. This alteration results from a G to A substitution at nucleotide position 950, causing the glycine (G) at amino acid position 317 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
