Risk genes associated with pediatric-onset MS but not with monophasic acquired CNS demyelination
Bibliographic record
Abstract
OBJECTIVE: To investigate whether 57 genetic risk loci recently identified in a large-scale genome-wide association study in adult patients with multiple sclerosis (MS) are also associated with a risk for pediatric-onset MS and whether they can predict MS diagnosis in children presenting with acquired demyelinating syndromes (ADS). METHODS: We included 188 children with ADS, of whom 53 were diagnosed with MS, 466 patients with adult-onset MS, and 2,046 adult controls in our cohort study. Weighted genetic risk scores (wGRS) were calculated to evaluate genetic effects. RESULTS: Mean wGRS was significantly higher for patients with pediatric-onset MS (7.32 ± 0.53) as compared with patients with monophasic ADS (7.10 ± 0.47, p = 0.01) and controls (7.11 ± 0.53, p < 0.01). We found no difference in mean wGRS of participants with monophasic ADS (7.10 ± 0.47) and controls (7.11 ± 0.53). The ability of the wGRS for the 57 single nucleotide polymorphisms (SNPs) to discriminate between children with MS and those with monophasic ADS was moderate (area under the curve [AUC] = 0.64), but improved with the addition of sex and HLA-DRB1*15 (AUC = 0.70). The combined effect of 57 SNPs exceeded the effect of HLA-DRB1*15 alone in our risk models for pediatric- and adult-onset MS. CONCLUSION: The previously reported 57 SNPs for adult-onset MS also confer increased susceptibility to pediatric-onset MS, but not to monophasic ADS.

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.
