Abstract

fetched live from OpenAlex

Myotonic dystrophy is an autosomal dominant disorder characterized by myotonia, progressive muscle wasting, and cataracts. There are two forms identified: myotonic dystrophy type 1 (DM1), caused by an expansion of a CTG repeat in the 3' untranslated region of the myotonin-protein kinase (DMPK) gene on chromosome 19, and myotonic dystrophy type 2 (DM2), caused by an expansion of a CCTG repeat in intron 1 of the cellular nucleic acid-binding protein (CNBP) gene on chromosome 3. There is no single method that can identify all ranges of repeats in both disorders. Protocols in this unit describe the analysis of PCR-amplified CTG repeats from the DMPK gene and CCTG repeats from the CNBP gene, respectively, using a fluorescent-labeled primer followed by capillary electrophoresis. An additional protocol describes the analysis of genomic DNA by Southern blot and hybridization for DM1, while yet another describes a similar technique to analyze the repeat in DM2 using field-inversion gel electrophoresis. Both techniques identify 100% of cases of these two disorders.

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. 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.
