Norwegian Family with Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay. PLoS ONE 8(6): e66145. doi:10.1371/journal.pone.0066145
Bibliographic record
Abstract
We employed whole exome sequencing to investigate three Norwegian siblings with an autosomal recessive spastic ataxia and epilepsy. All patients were compound heterozygous (c.13352T.C, p.Leu4451Pro; c.6890T.G, p.Leu2297Trp) for mutations in the SACS gene establishing the diagnosis of autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). The clinical features shown by our patients were typical of this disorder with the exception of epilepsy, which is a rare manifestation. This is the first report of ARSACS in Scandinavian patients and our findings expand the genetic and clinical spectrum of this rare disorder. Moreover, we show that exome sequencing is a powerful and cost-effective tool for the diagnosis of genetically heterogeneous disorders such as the hereditary ataxias.

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.
