Boy with 47,XXY,del(15)(q11.2q13) karyotype and Prader–Willi syndrome: A new case and review of the literature
Bibliographic record
Abstract
We report on a 10-year-old boy with a 47,XXY,del(15)(q11.2q13) karyotype and a Prader-Willi syndrome phenotype. His medical history and physical examination conformed to all of the major clinical criteria for Prader-Willi syndrome, but his height was taller than expected based on his hand and foot sizes. The deleted chromosome 15 was paternal in origin and molecular analysis showed maternal origin for the additional X chromosome. These findings suggest that the presence of these two disorders was coincidental in our patient. This supports the findings in the two other 47,XXY and Prader-Willi cases for which parent of origin studies have been published. Given the information from the literature and presented herein, we suggest that genetic counseling for cases of PWS and 47,XXY should address these two conditions separately.

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.
