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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.05567667).

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000144 (22/152362) while in subpopulation SAS AF= 0.00124 (6/4826). AF 95% confidence interval is 0.000541. There are 1 homozygotes in gnomad4. There are 9 alleles in male gnomad4 subpopulation. This position pass quality control queck.

The c.1960G>A (p.A654T) alteration is located in exon 12 (coding exon 12) of the STIM1 gene. This alteration results from a G to A substitution at nucleotide position 1960, causing the alanine (A) at amino acid position 654 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 654 of the STIM1 protein (p.Ala654Thr). This variant is present in population databases (rs201466902, gnomAD 0.05%). 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: 530877). 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. -
