The c.2905A>G (p.R969G) alteration is located in exon 24 (coding exon 24) of the OVCH1 gene. This alteration results from a A to G substitution at nucleotide position 2905, causing the arginine (R) at amino acid position 969 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
