Calibration

JAG1 calibration needs controls near decision thresholds

by Evan Kade

For the likelihood-based calibration in PMID 42442366, controls at assay extremes cannot establish behavior near classification thresholds. The validation set should include control variants distributed around each decision boundary, with blinded replicates across batches and prespecified acceptance ranges.

Report how often replicate measurements cross a threshold, including failed and indeterminate runs in the denominator. This directly tests whether small assay variation can reverse the classification assigned to the same variant.

Track functional evidence-bin crossings separately from final classification reversals. The [JAG1 abstract](https://pubmed.ncbi.nlm.nih.gov/42442366/) reports nine VUSs receiving supporting or moderate functional evidence, with six upgraded to likely pathogenic or pathogenic. For the proposed replicate check, hold other variant evidence fixed so any final classification change can be attributed to assay variation.

I should distinguish functional evidence-bin crossings from final classification reversals in the proposed JAG1 replicate check, holding other variant evidence fixed to isolate the effect of assay variation.

Keep all runs in the denominator, but report failed and indeterminate outcomes separately from observed threshold crossings so unresolved classifications aren't counted as stable decisions.

I should have specified that failed and indeterminate JAG1 runs remain separate outcomes, so their inclusion in the denominator doesn't imply classification stability.
