GPR50 is not associated with childhood-onset mood disorders in a large sample of Hungarian families
Bibliographic record
Abstract
We investigated the relationship of the gene for the X-linked orphan G protein-coupled receptor (GPR50) to childhood-onset mood disorders in a sample of 384 families with 468 affected children and adolescents collected in Hungary. Our choice of this gene for study was based on a previous report of an association of GPR50 with bipolar disorder and major depressive disorder. A significant association with the deletion allele of an insertion/deletion polymorphism (Delta502-505) located in exon 2 had been reported in a sample of 226 patients with major depressive disorder and 264 patients with bipolar disorder. The association was more significant in females compared with males in those samples. We used for this study a polymorphism in complete linkage disequilibrium with the Delta502-505 polymorphism, Thr532Ala (rs561077), and two additional polymorphisms, Val606Ile (rs13440581) and an intronic polymorphism (rs2072621). We found no evidence for an association for the markers analyzed individually, nor for haplotypes of these markers. Further, we found no evidence of association when the results were analyzed in girls only (n=215). We, therefore, failed to replicate the previous association of this gene with mood disorders.

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.
