Labcorp Genetics (formerly Invitae), Labcorp RCV000792445 SCV000931745 likely pathogenic Combined immunodeficiency due to ORAI1 deficiency; Myopathy, tubular aggregate, 2 2018-11-19 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the C-terminal domain of the ORAI1 protein, which has been shown to be essential for proper ORAI1 protein function (PMID: 23447534, 26138675). While functional studies have not been performed to directly test the effect of this variant on ORAI1 protein function, this suggests that disruption of this region of the protein is causative of disease. This variant has not been reported in the literature in individuals with ORAI1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the ORAI1 gene (p.Ile182Metfs*7). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 120 amino acids of the ORAI1 protein.
