The c.958G>A (p.G320R) alteration is located in exon 9 (coding exon 9) of the OVCH2 gene. This alteration results from a G to A substitution at nucleotide position 958, causing the glycine (G) at amino acid position 320 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
