Genes affected

NUP93 (HGNC:28958): (nucleoporin 93) The nuclear pore complex is a massive structure that extends across the nuclear envelope, forming a gateway that regulates the flow of macromolecules between the nucleus and the cytoplasm. Nucleoporins are the main components of the nuclear pore complex in eukaryotic cells. This gene encodes a nucleoporin protein that localizes both to the basket of the pore and to the nuclear entry of the central gated channel of the pore. The encoded protein is a target of caspase cysteine proteases that play a central role in programmed cell death by apoptosis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2016]

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. -
