Prenatal diagnosis of holoprosencephaly (HPE) in a fetus with a recombinant (18)dup(18q)inv(18)(p11.31q11.2)mat
Bibliographic record
Abstract
Alobar holoprosencephaly (HPE) was identified by ultrasonography at 18 weeks' gestation in a fetus of a 29-year-old G2P0A1 woman. HPE has been described in association with various chromosomal anomalies. Amniocentesis was performed and a rearrangement of chromosome 18 resembling an isochromosome for the long arm of chromosome 18 was found. Subsequently, the mother was found to have a pericentric inversion of chromosome 18 with breakpoints at p11.31 and q11.2. The karyotype of the fetus was re-interpreted as 46,XX, rec(18)dup(18q)inv(18)(p11.31q11.2)mat. This is the first case of a parental inversion leading to a deficiency of 18p11.31 to 18pter associated with HPE.

How this classification was reachedexpand
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.
