Genes affected
NFKBIA (HGNC:7797): (NFKB inhibitor alpha) This gene encodes a member of the NF-kappa-B inhibitor family, which contain multiple ankrin repeat domains. The encoded protein interacts with REL dimers to inhibit NF-kappa-B/REL complexes which are involved in inflammatory responses. The encoded protein moves between the cytoplasm and the nucleus via a nuclear localization signal and CRM1-mediated nuclear export. Mutations in this gene have been found in ectodermal dysplasia anhidrotic with T-cell immunodeficiency autosomal dominant disease. [provided by RefSeq, Aug 2011]

Ectodermal dysplasia and immunodeficiency 2 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 28, 2025This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 146 of the NFKBIA protein (p.Thr146Ile). This variant is present in population databases (rs753691609, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with NFKBIA-related conditions. ClinVar contains an entry for this variant (Variation ID: 583048). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
