Rod‐cone dystrophy in an adult with <scp><i>GNB1</i></scp>‐related disorder: An expansion of the phenotype and natural history
Bibliographic record
Abstract
Abstract GNB1‐related disorder is characterized by intellectual disability, abnormal tone, and other variable neurologic and systemic features. GNB1 encodes the β1 subunit of the heterotrimeric G‐protein, a complex with a key role in signal transduction. Consistent with its particularly high expression in rod photoreceptors, Gβ1 forms a subunit of retinal transducin (Gαtβ1γ1), which mediates phototransduction. In mice, GNB1 haploinsufficiency has been associated with retinal dystrophy. In humans, however, although vision and eye movement abnormalities are common in individuals with GNB1‐related disorder, rod‐cone dystrophy is not yet an established feature of this condition. We expand the phenotype of GNB1‐related disorder with the first confirmed report of rod‐cone dystrophy in an affected individual, and contribute to a further understanding of the natural history of this condition in a mildly affected 45‐year‐old adult.

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.
