Abstract

fetched live from OpenAlex

Abstract Linkage mapping refers to the specification of a particular chromosomal segment or segments within the genome that carry a causal DNA variant or mutation leading to a biological phenotype of interest. The appropriate chromosomal segment is determined through the use of anonymous polymorphic DNA markers as tags in different individuals who share the phenotype. Statistical analysis of data is usually critical in the determination. For whole‐genome linkage analysis, the most commonly used polymorphic markers are short tandem repeats, known as microsatellites or STRs. The experimental use of these markers has many subtleties and pitfalls, which are reviewed. Successful linkage mapping for a phenotypic trait is followed by the process of positional cloning, whereby the true underlying genetic variant is discovered. The final step from anonymous chromosomal segment to sequence variant detection can be relatively straightforward or highly demanding, depending on the complexity of the phenotype, the severity of the mutation in affecting gene function, and the extent to which carriers of the mutation are predisposed to the phenotype.

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.
