Abstract
PURPOSE: To investigate the possibility of duplications or deletions within the CHM gene as a cause of choroideremia (CHM). MATERIALS AND METHODS: Eight males and one female subject were identified in whom clinical features were consistent with a clinical diagnosis of CHM. In all cases, sequencing of the coding region and adjacent intronic splice sites did not identify a mutation. In some cases, supplemental immunoblot analysis of protein from peripheral blood leukocytes with anti-REP-1 antibody confirmed absence of Rab escort protein-1, REP-1. A multiplex ligation-dependent probe amplification assay (MLPA) for the CHM gene was developed to test for deletions and duplications within the CHM gene. RESULTS: A duplication of exons 3-8 of the CHM gene (NM_000390.2) was identified in one case. DISCUSSION: While likely an uncommon event, duplication within the CHM gene could be considered as an explanation for CHM cases in which no mutation is found by sequence analysis.

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 it
