Ambry Genetics

Nov 27, 2024

The c.2743A>G (p.R915G) alteration is located in exon 22 (coding exon 22) of the OVCH1 gene. This alteration results from a A to G substitution at nucleotide position 2743, causing the arginine (R) at amino acid position 915 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
