Genes affected
NFKB2 (HGNC:7795): (nuclear factor kappa B subunit 2) This gene encodes a subunit of the transcription factor complex nuclear factor-kappa-B (NFkB). The NFkB complex is expressed in numerous cell types and functions as a central activator of genes involved in inflammation and immune function. The protein encoded by this gene can function as both a transcriptional activator or repressor depending on its dimerization partner. The p100 full-length protein is co-translationally processed into a p52 active form. Chromosomal rearrangements and translocations of this locus have been observed in B cell lymphomas, some of which may result in the formation of fusion proteins. There is a pseudogene for this gene on chromosome 18. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.74T>C (p.V25A) alteration is located in exon 3 (coding exon 2) of the NFKB2 gene. This alteration results from a T to C substitution at nucleotide position 74, causing the valine (V) at amino acid position 25 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Immunodeficiency, common variable, 10 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 22, 2023An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. 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. ClinVar contains an entry for this variant (Variation ID: 657769). This variant has not been reported in the literature in individuals affected with NFKB2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 25 of the NFKB2 protein (p.Val25Ala). -
