Two Sisters with Congenital Blindness caused by Osteoporosis‐pseudoglioma Syndrome due to new Mutations in the <scp>LPR</scp>5 Gene
Bibliographic record
Abstract
Purpose To discover the reason behind two sisters being born blind with retinal detachment and microphthalmia with later findings of severe osteoporosis with low impact fractures Methods Molecular testing identified biallelic lipoprotein receptor‐related protein 5 (LRP5) mutations (NM_002335.3:c. [889dupA]; [2827 + 1G4A]) confirming a diagnosis of osteoporosis–pseudoglioma (OPPG) syndrome. Results Two new mutations in the LPR5 gene were each found in the unrelated parents of the girls and were found heterozygote in the girls. Both parents were then discovered to have osteopenia, as did several relatives, who all started preventive treatment. Conclusions OPPG is a autosomal recessive disease almost uniformly causing blindness from very early age with severe osteoporosis and low impact fractures, which was also the case of our two sisters. The diagnosis of OPPG was confirmed by sequencing the LPR5 gene, where two new mutations were found.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
