GeneDx RCV000187697 SCV000241294 likely pathogenic not provided 2016-03-09 criteria provided, single submitter clinical testing The V620M variant in the GRIN2B gene has not been reported previously as a pathogenic varaint nor as a benign polymorphism, to our knowledge. The V620M variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The V620M variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution is predicted to occur at a position within the cytoplasmic domain that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Therefore this variant is likely pathogenic; however the possibility that is benign cannot be excluded.
