RCV002937433 | SCV003258753 | uncertain significance | Stormorken syndrome; Combined immunodeficiency due to STIM1 deficiency; Myopathy with tubular aggregates | 2023-12-12 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 307 of the STIM1 protein (p.Thr307Ala). This variant is present in population databases (rs773169744, gnomAD 0.004%). 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: 2050080). 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. |
| Ambry Genetics | RCV003167947 | SCV003898551 | uncertain significance | Inborn genetic diseases | 2023-02-13 | criteria provided, single submitter | clinical testing | The c.919A>G (p.T307A) alteration is located in exon 7 (coding exon 7) of the STIM1 gene. This alteration results from a A to G substitution at nucleotide position 919, causing the threonine (T) at amino acid position 307 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
