GeneDx RCV000189178 SCV000242810 uncertain significance not provided 2013-10-10 criteria provided, single submitter clinical testing p.Phe1812Ile (TTT>ATT): c.5434 T>A in exon 27 of the SCN2A gene (NM_021007.2). The Phe1812Ile 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. In silico analysis predicts this variant is probably damaging to the protein structure/function. It alters a conserved position in the C-terminus of the protein, however very few mutations have been reported in this region of the gene. Therefore, based on the currently available information, it is unclear whether Phe1812Ile is a disease-causing mutation or a rare benign variant. The variant is found in CHILD-EPI panel(s).
