Genes affected

ORAI1 (HGNC:25896): (ORAI calcium release-activated calcium modulator 1) The protein encoded by this gene is a membrane calcium channel subunit that is activated by the calcium sensor STIM1 when calcium stores are depleted. This type of channel is the primary way for calcium influx into T-cells. Defects in this gene are a cause of immune dysfunction with T-cell inactivation due to calcium entry defect type 1 (IDTICED1).

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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This sequence change replaces proline, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 47 of the ORAI1 protein (p.Pro47Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ORAI1-related conditions. -
