Ambry Genetics

Nov 01, 2022

The c.1684A>G (p.M562V) alteration is located in exon 11 (coding exon 11) of the CPXM2 gene. This alteration results from a A to G substitution at nucleotide position 1684, causing the methionine (M) at amino acid position 562 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
