Likely pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Dec 10, 2021 | Published functional studies demonstrate a damaging effect; this variant fails to interact and reduces translocation of SMAD4 (Braun et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function and splicing; This variant is associated with the following publications: (PMID: 31517150, 30577294, 26878725, 33578576, 29869118, 33532864) - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 22, 2024 | This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 591 of the NUP93 protein (p.Gly591Val). This variant is present in population databases (rs145473779, gnomAD 0.03%). This missense change has been observed in individual(s) with steroid-resistant nephrotic syndrome (PMID: 26878725). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 224964). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NUP93 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects NUP93 function (PMID: 26878725). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic. - |
