Complex mosaicism in sex reversed <i>SRY</i>+ male twins
Bibliographic record
Abstract
Sex reversal is characterized by discordance between genetic and phenotypic sex. Most XX males result from an unequal interchange between X and Y chromosomes during paternal meiosis, therefore transferring SRY to the X chromosome, which explains the male development in the presence of an otherwise normal female karyotype. We present here the case of sex reversed SRY+ male twins with several cell lines. They consulted for infertility. The presence of SRY on an X chromosome was demonstrated by FISH. Their respective karyotypes were: 46,X,der(X)t(X;Y)(p22.3;p11.2)[249]/45,X [12]/45,der(X)t(X;Y)(p22.3;p11.2)[11]/47,XX,der(X)t(X;Y) (p22.3;p11.2)[1]/47,X,der(X)t(X;Y)(p22.3;p11.2)x2[1]/50, XX,der(X)t(X;Y)(p22.3;p11.2)x4[1]/46,XX[1] for the first twin (SH-1) and 46,X,der(X)t(X;Y)(p22.3;p11.2)[108]/45,X [3]/47,XX,der(X)t(X;Y)(p22.3;p11.2)[2]/45,der(X)t(X;Y) (p22.3;p11.2)[1]/47,X,der(X)t(X;Y)(p22.3;p11.2)x2[1] for the second twin (SH-2). There are three different types of XX males: 1) with normal genitalia, 2) with genital ambiguity, and 3) XX true hermaphrodites. The phenotype of the twins presented in this report is consistent with what is generally seen in XX SRY+ males: they have normal genitalia.

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.
