Fcγ Receptor Polymorphisms Do Not Predict Response to Intravenous Immunoglobulin in Myasthenia Gravis
Bibliographic record
Abstract
We studied 63 patients with myasthenia gravis (MG) requiring treatment with intravenous immunoglobulin, to determine if polymorphisms within the FCγR2A (rs1801274), FCγR2B (rs1050501), FCγR3A (rs396991), and FCγR3B (NA1/NA2) genes are correlated with response to treatment. There was no significant difference in any of the polymorphisms studied between responders and nonresponders. Patients with the FCγR2B-232I/I polymorphism had higher disease severity measured by the quatitative myasthenia gravis score (QMGS). There was no difference in the distribution of the FCγR2B-232 polymorphisms between the patients and 90 healthy controls. The finding of greater disease severity in patients with the FCγR2B-232I/I polymorphism requires confirmation in a larger population of patients with myasthenia gravis.

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.
