A Locus for Primary Lateral Sclerosis on Chromosome 4ptel-4p16.1
Bibliographic record
Abstract
BACKGROUND: Primary lateral sclerosis (PLS) is an adult-onset upper motor neuron disease resulting in spinal and bulbar spasticity. A family with 8 individuals diagnosed with PLS was previously reported. OBJECTIVE: To identify a locus for a large family with PLS. METHODS: A 550-marker whole-genome scan was performed on this family followed by fine mapping with sequence-tagged site markers to identify a candidate region. RESULTS: A locus was identified for this family between the telomere of chromosome 4 and marker D4S2928 (4ptel-4p16.1). A maximum lod score of 3.01 was obtained for marker D4S2936. The region spans 23.17 cM (10.2 megabase pairs) and encompasses 130 genes. CONCLUSIONS: PLS1 does not map near any other identified loci for upper or lower motor neuron diseases and thus represents a novel locus for PLS.

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.
