Labcorp Genetics (formerly Invitae), Labcorp RCV002235470 SCV000965383 uncertain significance Stormorken syndrome; Combined immunodeficiency due to STIM1 deficiency; Myopathy with tubular aggregates 2018-07-09 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with STIM1-related disease. 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 missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with aspartic acid at codon 99 of the STIM1 protein (p.His99Asp). The histidine residue is moderately conserved and there is a moderate physicochemical difference between histidine and aspartic acid.
