Abstract
Panic disorder is classified as an anxiety disorder and affects 1-3% of the population. An individual suffering from such a disorder may experience unexpected recurrent panic attacks and fear of future attacks. Twin and family studies have pointed towards a strong heritability of the disorder. Stress response and anxiety are thought to be mediated, at least in part, by the corticotrophin-releasing hormone (CRH), which is known to be a regulator of the hypothalamic-pituitary-adrenal pathway. To search for markers conferring genetic susceptibility to panic disorder, we typed three polymorphisms of the CRHR2 gene - CRHR2(CA), CRHR2(GT), and CRHR2(GAT) - in 466 individuals, 183 of whom had DSM-IV panic disorder. Seventy-five case-controls and 101 triad families plus 13 siblings were examined. Case-control association analyses using chi(2) tests yielded no difference in the distribution of the alleles. Linkage analysis using the Transmission Disequilibrium Test showed no preferential transmission of alleles for any of the three markers. Haplotype analysis indicated that allele 7 of CRHR2 (GAT) and 8 of CRHR2 (GT) are in almost complete linkage disequilibrium (P = 0.000 000 1). Although both neurobiology and chromosomal location point to the CHRH2 receptor gene as a candidate for panic disorder, our study indicates that the CRHR2 polymorphisms examined do not confer susceptibility to panic disorder. Further studies investigating additional polymorphisms in this gene and other components of the CRH signalling system may prove useful.

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
