This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 109 of the STIM1 protein (p.His109Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with tubular aggregate myopathy (TAM) (PMID: 23332920, 24570283). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 41483). 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: 23332920). For these reasons, this variant has been classified as Pathogenic. -
