GeneDx RCV000478589 SCV000569377 uncertain significance not provided 2019-07-22 criteria provided, single submitter clinical testing In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV002525840 SCV003519138 uncertain significance Cortical dysplasia-focal epilepsy syndrome 2022-03-11 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 857 of the CNTNAP2 protein (p.Ser857Phe). This variant is present in population databases (rs200330677, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with CNTNAP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 420513). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
