Clinical characteristics in patients with interstitial deletions of chromosome region 12q21–q22 and identification of a critical region associated with keratosis pilaris
Bibliographic record
Abstract
We report on a male patient with a submicroscopic 1.21 Mb de novo deletion at 12q21.33-q22 with global developmental delay, characteristic facial features, and keratosis pilaris. Thus far, five other cases with a 12q de novo deletion including this segment have been reported; our case represents the smallest de novo deletion within this chromosome region. High resolution SNP microarray analysis showed a deletion of RefSeq genes BTG1 and LOC256021, and partial deletion of DCN. We propose that BTG1 is a critical gene for the development of the distinctive keratosis pilaris observed in patients with interstitial deletion of 12q21-q22, and suggest candidate genes that may contribute to dysmorphic features and global developmental delay.

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.
