Labcorp Genetics (formerly Invitae), Labcorp RCV002050453 SCV002318212 uncertain significance Stormorken syndrome; Combined immunodeficiency due to STIM1 deficiency; Myopathy with tubular aggregates 2021-04-13 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with STIM1-related conditions. This variant is present in population databases (rs755714206, ExAC 0.001%). This sequence change replaces methionine with valine at codon 245 of the STIM1 protein (p.Met245Val). The methionine residue is moderately conserved and there is a small physicochemical difference between methionine and valine.
