Genes affected

STIM1 (HGNC:11386): (stromal interaction molecule 1) This gene encodes a type 1 transmembrane protein that mediates Ca2+ influx after depletion of intracellular Ca2+ stores by gating of store-operated Ca2+ influx channels (SOCs). It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocrotical carcinoma, and lung, ovarian, and breast cancer. This gene may play a role in malignancies and disease that involve this region, as well as early hematopoiesis, by mediating attachment to stromal cells. Mutations in this gene are associated with fatal classic Kaposi sarcoma, immunodeficiency due to defects in store-operated calcium entry (SOCE) in fibroblasts, ectodermal dysplasia and tubular aggregate myopathy. This gene is oriented in a head-to-tail configuration with the ribonucleotide reductase 1 gene (RRM1), with the 3' end of this gene situated 1.6 kb from the 5' end of the RRM1 gene. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]

Collection Method: clinical testing

The missense variant c.22G>A (p.Ala8Thr) in STIM1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant has been reported to the ClinVar database as Uncertain Significance. The p.Ala8Thr variant is novel (not in any individuals) in 1000 Genomes and allele frequency of 0.0007955% is reported in gnomAD. The amino acid Ala at position 8 is changed to a Thr changing protein sequence and it might alter its composition and physico-chemical properties. The variant is predicted to be damaging by PolyPhen2 and the residue is conserved across species. The amino acid change p.Ala8Thr in STIM1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as uncertain significance . -

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 8 of the STIM1 protein (p.Ala8Thr). This variant is present in population databases (rs751520286, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with STIM1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1035654). 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. 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. -
