Karyotype/phenotype correlation in partial trisomies of the long arm of chromosome 16: Case report and review of literature
Bibliographic record
Abstract
Trisomy 16q is a clinically recognizable entity presenting with a wide spectrum of abnormalities. Only five infants with a diagnosis of partial trisomy 16q13 → qter have been previously reported, and all died during the first year of life. We report the clinical and molecular cytogenetic findings in a patient with trisomy 16q13 → qter due to the presence of a supernumerary marker chromosome (SMC). The child presented with microcephaly, ambiguous genitalia, cardiac malformations and dysmorphic features. Cytogenetic investigation using GTG-banding, spectral karyotyping (SKY) and fluorescence in situ hybridization analyses revealed an SMC of maternal origin with karyotype der(15)t(15;16)(q13;q13). Specific genotype-phenotype correlations among different segments of the 16q region cannot yet be defined. We suggest that the involvement of the entire region spanning from 16q11 to 16q22 is necessary for the characteristic phenotype of the trisomy 16q.

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.
