Abstract

fetched live from OpenAlex

Purpose To describe a case of high myopia in a pediatric patient with a mutation in the OTX2 gene and further characterize the diverse ocular phenotypes of heterozygous OTX2 mutations.Patient and Methods We describe a three-year-old girl who presented at two months old with abnormal eye movements and suspected retinal dystrophy. Clinical exam and electroretinography (ERG) were conducted, and molecular next generation sequencing (NGS) with the Inherited Retinal Dystrophies panel was completed in our patient and offered to the family.Results Further examination revealed progressive high myopia in our patient and her mother, alongside diffuse retinal thinning and normal ERG. NGS identified a likely pathogenic variant in the OTX2 gene (c.235 G > A) that was maternal in origin. There were no extra-ocular concerns in our patient, and brain MRI was normal.Conclusions While OTX2 mutations are known to cause retinopathy, this case presents a unique phenotype through a heterozygous missense variant (c.235 G > A) underlying high myopia in a three-generation family. This case further supports the role of OTX2 in ocular development and demonstrates the variable expressivity of OTX2 mutations. Genetic testing in families with high myopia may be useful in future surveillance and preparation for ocular and extra-ocular complications associated with OTX2-syndrome presentations.

Teacher imitation

Not 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.
