GeneDx RCV000189285 SCV000242917 pathogenic not provided 2013-10-18 criteria provided, single submitter clinical testing p.Ala1650Val (GCC>GTC): c.4949 C>T in exon 27 of the SCN8A gene (NM_014191.3). The Ala1650Val missense change 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. This variant is a conservative substitution of one uncharged, non-polar amino acid for another. It alters a highly conserved position between the S4 and S5 subunits of the forth transmembrane domain. In silico analysis predicts this variant is probably damaging to the protein structure/function. This variant has been observed de novo without verified parentage. The variant is found in EPILEPSY panel(s).
