This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 426 of the STIM1 protein (p.Arg426Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of autosomal recessive STIM1 deficiency (PMID: 24621671). ClinVar contains an entry for this variant (Variation ID: 375470). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on STIM1 protein function. Experimental studies have shown that this missense change affects STIM1 function (PMID: 32098964, 35724962). 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. -
