Common variable immunodeficiency (CVID) with central adrenal insufficiency is a recently defined clinical syndrome caused by mutations in the nuclear factor kappa-B subunit 2 (NFKB2) gene. We present the first case of NFKB2 mutation in Asian population.Methods and Results
An 18-year-old Chinese female with adrenocorticotropic hormone (ACTH) deficiency was admitted due to adrenal crisis and pneumonia. She had a history of recurrent respiratory infections since childhood and ectodermal abnormalities were noted during physical examination. Immunologic tests revealed panhypogammaglobulinemia and deficient natural killer (NK)-cell function. DNA sequencing of NFKB2 identified a heterozygous nonsense mutation (c.2563 A>T, p.855: Lys>*) in the patient but not her parents.Conclusion
Clinicians should be alert to comorbidities of adrenal insufficiency and ectodermal dysplasia in CVID patients as these might suggest a rare hereditary syndrome caused by NFKB2 mutation.
