Ambry Genetics

Feb 16, 2023

The c.1928G>A (p.G643D) alteration is located in exon 13 (coding exon 13) of the CPXM2 gene. This alteration results from a G to A substitution at nucleotide position 1928, causing the glycine (G) at amino acid position 643 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
