Ambry Genetics

Jul 12, 2022

The c.721A>G (p.M241V) alteration is located in exon 3 (coding exon 2) of the PSD2 gene. This alteration results from a A to G substitution at nucleotide position 721, causing the methionine (M) at amino acid position 241 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
