Ataxie de Friedreich : une maladie mitochondrialedue à une perturbation de l’homéostasie du fer dans les mitochondries
Bibliographic record
Abstract
L’ataxie de Friedreich represente la plus frequente des ataxies hereditaires humaines. C'est une maladie neurodegenerative autosomique recessive touchant environ une personne sur 50 000, soit 1 500 a 2 000 personnes actuellement en France. L'atteinte neurologique s'accompagne dans une majorite des cas d'une atteinte cardiaque qui peut se reveler fatale. En 1996, le gene responsable de l'ataxie de Friedreich etait identifie par un travail en collaboration des equipes francaise et canadienne de Michel Koenig et Massimo Pandolfo [1]. Ces equipes ont montre pour la premiere fois dans une maladie genetique autosomique recessive la responsabilite d'une expansion de triplets dans un gene, celui de la frataxine. L'expansion presente dans le premier intron du gene est retrouvee chez plus de 95 % des patients et varie de 170 a 1 000 chez les malades contre 7 a 25 dans la population normale. L'expansion entraine une diminution quantitative du messager de la frataxine resultant en une perte de fonction de la proteine.

How this classification was reachedexpand
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.
