Abstract
Abstract Androgen insensitivity is an X‐linked disorder of defective or absent virilisation in 46, XY individuals due to complete or partial resistance to androgens in androgen‐dependent tissues and organs. The syndrome is part of a scala of disorders of sex development (DSD). The molecular cause of the syndrome is mutations in the androgen receptor gene (locus: Xq11.2–12), resulting either in absence of an androgen receptor protein or in production of a mutant androgen receptor protein with partial or complete loss of its activity. Androgen insensitivity displays a broad phenotypic and genotypic spectrum. The phenotype can vary from a complete form (CAIS, complete androgen insensitivity syndrome), partial form (PAIS, partial androgen insensitivity syndrome) to a mild form (MAIS, mild androgen insensitivity syndrome). More than 400 different mutations in the androgen receptor gene have been reported. The majority of mutations are single‐base substitutions. However, deletions (1–6 base pairs), partial or complete gene deletions (>10 base pairs), insertions or duplications are also found. Mutations are compiled in the androgen receptor database ( www.mcgill.ca/androgendb ). Key Concepts: Androgens and the androgen receptor are indispensable for expression of the male phenotype. The androgen receptor is a ligand‐dependent transcription factor and belongs to the family of nuclear receptors. Despite two different ligands (testosterone and 5α‐dihydrotestosterone), only one androgen receptor cDNA has been identified and cloned. A highly polymorphic (CAG) n ‐CAA repeat, encoding a polyglutamine stretch, in exon 1 of the androgen receptor gene is used for identification of X‐chromosomes for carrier detection in pedigree analyses. Variations in the polyglutamine stretch modulate androgen receptor transcriptional activity. End‐organ resistance to androgens has been designated as androgen insensitivity syndrome (AIS) and is distinct from other XY disorders of sex development. Defects in the androgen receptor gene can prevent normal development of both internal and external male structures in 46, XY individuals. End‐organ resistance to androgens is X‐linked and only 46, XY individuals are affected. AR gene mutations are transmitted in an X‐linked manner, but in 30% of the cases, mutations arise de novo . Androgen insensitivity can be routinely analysed and differential diagnosis is possible with other syndromes presenting with almost similar phenotypes.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
