Abstract
In Brief Purpose: To describe a de novo gene mutation in a female patient with clinically characteristic findings of choroideremia (CHM). Methods: Determination of best-corrected visual acuity, fundus examination, visual field analysis, and electroretinography were performed on a female patient with an advanced CHM phenotype. Blood samples were obtained from the patient and both her parents, and direct genomic sequencing for DNA analysis was performed on the blood samples. Results: A single base-pair sequence change was identified in codon 293 in exon 7 (R293X) of the CHM gene in the proband. This mutation was not found to occur in her clinically unaffected parents. Conclusion: These findings document that a de novo point mutation should be considered when an isolated female family member is found to have CHM. Best-corrected visual acuity measurement, fundus examination, visual field analysis, and electroretinogram testing were performed for a woman with an advanced choroideremia (CHM) phenotype. Blood samples were obtained from the patient and both her parents, and their DNA was analyzed by direct genomic sequencing. A single base-pair sequence change was identified in codon 293 in exon 7 (R293X) of the CHM gene in the proband. This mutation was not found to occur in her clinically unaffected parents. These findings document that a de novo point mutation should be considered when an isolated female family member is found to have CHM.

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
