RCV000493410 | SCV000582180 | likely pathogenic | not provided | 2015-09-24 | criteria provided, single submitter | clinical testing | The Q901E variant has not been published as a pathogenic variant, nor has it been reported as a benign variant 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 Q901E variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution alters a conserved position predicted to be within transmembrane segment S5 in the second homologous domain of the SCN2A protein. In silico analysis predicts the Q901E variant is probably damaging to the protein structure/function. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded. |
