Abstract
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS; MIM SACS 270550) is frequent in northeastern Québec. Two causal mutations have been identified in the 11.7-kb single exon sacsin gene by sequence-based analyses. Mutation g.6594delT (DeltaT) was reported in 96% of the patients whereas a g.5254C --> T nonsense mutation has been observed only in 2 families. Here we report a reliable and inexpensive method to detect more than 95% of the ARSACS disease alleles from northeastern Québec using allele-specific oligonucleotide (ASO) hybridization. This procedure is being incorporated into the diagnosis of ARSACS, as well as being used for carrier detection in at-risk families from northeastern Québec.

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 it
