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).

Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 11, 2024This variant, c.85_99dup, results in the insertion of 5 amino acid(s) of the ORAI1 protein (p.Arg29_Arg33dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (no rsID available, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ORAI1-related conditions. ClinVar contains an entry for this variant (Variation ID: 541943). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
