Ambry Genetics

Nov 07, 2022

The c.22G>C (p.G8R) alteration is located in exon 1 (coding exon 1) of the RGPD4 gene. This alteration results from a G to C substitution at nucleotide position 22, causing the glycine (G) at amino acid position 8 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
