Deskripsi

B-cell lymphoma/leukemia 11B (BCL11B) is a C2H2 zinc finger transcription factor that is critically important for regulating the development and function of a variety of systems including the central nervous system, the skin, and the immune system. Germline heterozygous variants are associated with a spectrum of clinical disorders, including severe combined immunodeficiency as well as neurological, craniofacial, and dermal defects. Of these individuals, ~50% present with severe allergic disease. Here, we report the detailed clinical and laboratory workup of one of the most severe BCL11B-dependent atopic cases to date. Leveraging a zebrafish model, we were able to confirm a strong T-cell defect in the patient. Based on these data, we classify germline BCL11B-dependent atopic disease as a novel primary atopic disorder.
