GeneDx RCV000187684 SCV000241281 uncertain significance not provided 2014-04-16 criteria provided, single submitter clinical testing p.D1249N (GAT>AAT): c.3745 G>A in the GRIN2A gene (NM_000833.3). The D1249N variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. It was not observed in approximately 6,500 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 D1249N variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved in mammals. A missense mutations in a nearby residue (D1251N) has been reported in association with atypical rolandic epilepsy, supporting the functional importance of this region of the protein. However, in silico analysis predicts the D1249N variant likely does not alter the protein structure/function. The variant is found in INFANT-EPI panel(s).
