Identification of a novel <i>NFKB2</i> mutation in a patient presenting with autoimmune cytopenia and generalized granulomatous lymphadenopathy
Bibliographic record
Abstract
Introduction: NF-κB proteins are transcription factors that modulate various functions of the immune system. NF-κB2 (or p100/p52) has particularly important roles in B cell development and function. Primary immunodeficiency due to mutations in the NFKB2 gene, encoding NF-κB2, range from combined immunodeficiency with susceptibility to viral or opportunistic infections to primarily antibody deficiency. Methods: A comprehensive chart review of our patient was performed. Results: Our patient, currently a 19-year-old male, presented with multiple autoimmune cytopenia resistant to treatment and generalized granulomatous lymphadenopathy. Whole exome sequencing identified a novel pathogenic variant in NFKB2 (c.1700C>T; p.A567V) that is the cause of our patient’s presentation. Conclusion: We present a novel pathogenic variant in NFKB2 with an unusual presentation. Statement of novelty: Here, we report a novel mutation in NFKB2 and the clinical presentation of the affected patient, which helps in further understanding the NF-κB2 pathway and its associated disease.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
