Labcorp Genetics (formerly Invitae), Labcorp RCV003583659 SCV004301042 uncertain significance Severe combined immunodeficiency due to IKK2 deficiency 2024-01-22 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 271 of the IKBKB protein (p.Glu271Ala). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with IKBKB-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt IKBKB protein function with a negative predictive value of 95%. 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.
