A new variant database for mismatch repair genes associated with Lynch syndrome
Bibliographic record
Abstract
Mutations in some mismatch repair (MMR) genes are associated with Lynch syndrome (LS; also called hereditary nonpolyposis colorectal cancer [HNPCC]), an autosomal dominant cancer susceptibility syndrome. Colorectal cancer (CRC) is the most frequent cancer observed in LS. However, tumors occur at a variety of extracolonic sites and individuals may have multiple primary cancers. LS is the most common hereditary form of CRC, accounting for approximately 1% of all CRC. Since the first account of mutations in MSH2 causing this cancer susceptibility syndrome in 1993, mutations in three additional MMR genes, MLH1, MSH6, and PMS2, have been shown to cause LS. More than 1,500 different variants have been identified in these four genes and approximately 80% of the alterations have been identified in MLH1 and MSH2. There have been a few previous attempts to systematically record MMR variants associated with LS patients; however, they were not complete nor were they continuously updated. Thus, it was our goal to generate and maintain a comprehensive catalogue of MMR variants from genes known to be mutated in LS (http://www.med.mun.ca/MMRvariants; last accessed 8 February 2007). Providing such a resource should aid investigators in understanding the significance of the variants.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
