Abstract
Tourette syndrome (TS) is a complex neuropychiatric disorder with a strong genetic basis. Although no specific susceptibility genes have been identified for TS, cytogenetic studies in selected cases suggest the existence of a predisposing gene located in the 7q31 chromosomal region. In order to test the hypothesis of a possible relationship between this region and TS at the population level, we undertook a family based association study in a sample of French Canadian patients from Quebec. For this purpose, markers D7S522, D7S523, and D7S1516 were tested using the extended transmission disequilibrium test (e-TDT). Marker D7S522 showed a biased transmission of alleles from heterozygote parents to their TS offsprings (allele-wise TDT chi(2) = 12.61, 4 df, P = 0.013, genotype-wise TDT chi(2) = 15.49, 7 df, P = 0.030). When the analysis was restricted to patients without ADHD or OCD comorbidity, similar results were observed both allele and genotype-wise (chi(2) = 10.68, 4 df, P = 0.03 and chi(2) = 12.55, 5 df, P = 0.028, respectively). In addition, marker D7S523 was also associated (allele-wise TDT chi(2) = 18.37, 7 df, P = 0.01 and genotype-wise TDT chi(2) = 46.26, 17 df, P = 0.00016), and showed a tendency for association in the comorbidity-free subgroup (genotype-wise TDT chi(2) = 18.7, 10 df, P = 0.044). Finally, marker D7S1516, contained in the inner mitochondrial membrane peptidase 2 like (IMMP2L) gene, also showed a tendency for association (genotype-wise TDT chi(2) = 32.87, 21 df, P = 0.048). These results may reflect the proximity of markers D7S522, D7S523, and possibly D7S1516 to a gene or regulatory region relevant to TS predisposition.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
