Abstract

fetched live from OpenAlex

An accurate diagnosis is essential for effective medical management; in the case of rare genetic disease, it also guides genetic counseling. Nevertheless, clinical assessments and conventional genetic testing lead to a diagnosis in less than half of patients.1 The introduction of whole-exome sequencing has substantially improved our ability to provide patients with a molecular diagnosis and is increasingly the approach of choice for patients with rare diseases. With the genes known for more than half of the predicted 7000 rare diseases,2 such hypothesis-free approaches to diagnosis are attractive and have the potential to end the “diagnostic odyssey.”As clinicians, we . . .

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.

Not 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.
