Update on hereditary C1q deficiency: pathophysiology, clinical presentation, genotype and management
Bibliographic record
Abstract
PURPOSE OF REVIEW: C1q deficiency is a rare inborn error of immunity characterized by susceptibility to severe infections and profound immune dysregulation, with a systemic lupus erythematosus-like phenotype. The management of patients with C1q deficiency is challenged by the rarity of this condition and the wide clinical variability. This review aims to emphasize the importance of a thorough immunological and clinical characterization to help guide a personalized and comprehensive approach to patients. RECENT FINDINGS: We focus on the concept of C1q deficiency as a bridge between the monogenic form of systemic lupus erythematosus and the Mendelian type I interferonopathies. Moreover, we explore the role of new treatment strategies such as Janus-associated kinase (JAK) inhibitors and allogeneic stem cell transplantation. SUMMARY: In this narrative review, we provide a systematic overview of C1q deficiency, starting with the description of the pathophysiological background and the variable clinical phenotype, and then exploring the different prognoses, the consequent treatment strategies and future directions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
