Involvement of the Superior Cerebellar Peduncles in GAA- <i>FGF14</i> Ataxia
Bibliographic record
Abstract
Objectives: gene. After the clinical observation of superior cerebellar peduncle (SCP) involvement in some affected patients, we sought to verify the prevalence of this finding in our cohort and 4 additional independent cohorts of patients with SCA27B. Methods: We performed a retrospective review of the brain MRI scans of a total of 87 patients (median age at MRI 69 years; range 28-88 years) from different independent cohorts to assess the presence of SCP involvement, defined as abnormally high T2 signal along the SCP tract. Results: We observed SCP involvement in 52 patients (52/87; 59.8%) from all the cohorts combined. The finding was replicated at rates ranging from 50% to 62.8% in the cohorts taken separately. Discussion: SCP involvement in SCA27B is frequent. Its detection may facilitate the diagnostic process of patients with SCA27B.

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.
