Invitae RCV000531661 SCV000651819 uncertain significance Pitt-Hopkins-like syndrome 2 2023-10-03 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 945 of the NRXN1 protein (p.Asp945Asn). This variant is present in population databases (rs773147215, gnomAD 0.01%). 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: 472645). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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.
GeneDx RCV001799683 SCV002044055 uncertain significance not provided 2022-03-14 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Missense variant in a gene in which most reported pathogenic variants are truncating/loss-of-function; Has not been previously published as pathogenic or benign to our knowledge
