Ambry Genetics

Apr 12, 2022

The c.2154C>G (p.C718W) alteration is located in exon 14 (coding exon 14) of the RGS22 gene. This alteration results from a C to G substitution at nucleotide position 2154, causing the cysteine (C) at amino acid position 718 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
