Labcorp Genetics (formerly Invitae), Labcorp RCV001212462 SCV001384045 uncertain significance Severe combined immunodeficiency due to IKK2 deficiency 2019-09-26 criteria provided, single submitter clinical testing 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has been reported not to substantially affect IKBKB protein function (PMID: 30335863). This variant has not been reported in the literature in individuals with IKBKB-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with arginine at codon 301 of the IKBKB protein (p.Lys301Arg). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and arginine.
