Invitae RCV001209575 SCV001381017 uncertain significance Pitt-Hopkins-like syndrome 2 2022-04-29 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with histidine, which is basic and polar, at codon 830 of the NRXN1 protein (p.Asn830His). This variant has not been reported in the literature in individuals affected with NRXN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 940064). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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.
GeneDx RCV001560981 SCV001783496 uncertain significance not provided 2019-09-27 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
