Abstract

fetched live from OpenAlex

Improvement in localization of disease susceptibility genes by simultaneous consideration of multiple interacting loci was assessed using the Genetic Analysis Workshop 12 simulated data. Evidence of linkage at primary loci was used to weight families for analyses at secondary loci. To identify regions linked to disease susceptibility genes, parametric and allele-sharing genome scans were performed in the extended pedigrees and nuclear families, respectively. The position of the peak allele-sharing lod was used as the estimate of a disease gene location. In weighted analyses, the positions where the greatest lod increases occurred were taken as alternative estimates of the gene locations. Variability of the location estimates of disease genes given by the unweighted and weighted analyses was compared. Similar analyses were carried out using true disease loci to determine weights. Weighted analyses did not in general improve the localization of disease genes in this data set, even with a large sample of 1,928 nuclear families, due to the features of the underlying additive liability threshold model.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
