Retinoic Acid-Induced 1 gene variants associated with Smith–Magenis syndrome circadian phenotypes enriched in autism spectrum disorder: whole-genome sequencing study
Bibliographic record
Abstract
Abstract Background This study aimed to characterize the frequency of RAI1 genetic aberrations associated with Smith–Magenis syndrome (SMS), in a large cohort of autism spectrum disorder (ASD) whole-genome sequencing samples. We aimed to determine the frequencies of RAI1 single-nucleotide variants (SNVs) and copy number variants (CNVs). Results We report a 2.5 × enrichment of the major deletion and a > 5 × enrichment of the frameshift variants as compared to the known prevalence of SMS 1/15,000. Additionally, we report a significant enrichment of RAI1 rare missense variants in ASD subjects with respect to controls (54 variants/6080 ASD subjects and 6 variants/2541 controls, p-value < 0.002, OR 3.78, CI 1.62–8–81). Conclusions The SMS phenotype including circadian dysregulation and associated sleep disturbances is mainly caused by RAI1 haploinsufficiency. Sleep disturbances as seen in SMS may overlap in ASD, especially in patients with consequential variants in RAI1 gene.

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.
