Ectodermal dysplasia with immunodeficiency 2 (EDAID2) is characterized by variable features of ectodermal dysplasia (e.g., hypo-/anhidrosis, sparse hairiness, dental abnormalities) and various immunological and infectious phenotypes of varying severity (see Boisson et al. 2017). This phenotype of ectodermal dysplasia is associated with mutations in the NFKBIA gene.

DefinitionThis section has been translated automatically.
EtiopathogenesisThis section has been translated automatically.
Mutations in the NFKBIA gene result in functional impairment of NFKB, a master transcription factor required for normal activation of immune responses. Disruption of NFKB signaling leads to decreased production of proinflammatory cytokines and certain interferons, making patients susceptible to infection (McDonald et al. 2007).
