Abstract

fetched live from OpenAlex

Social phobia, particularly in its generalized form, has a genetic component in its etiology as suggested by positive twin studies and child temperament studies of social anxiety. Observations from functional imaging research suggest that dopamine function may be abnormal in the brains of patients with social phobia. Our investigation examined polymorphisms in the dopamine D2, D3 and D4 receptor genes, plus the dopamine transporter gene in a sample consisting of 17 multiplex social phobia families. We employed both parametric and non-parametric methods to test for linkage. Linkage was excluded for all loci under the broad diagnostic category. In the medium diagnostic category, the D3 receptor gene showed non-significant positive LOD scores (LOD = 0.62). We are able to clearly exclude a major effect for each of the four dopamine gene markers under the broad diagnosis of social phobia. Additional studies of dopamine system genes will be necessary to define clearly their role in social phobia.

Full frame distilled prediction

Teacher imitation

Not 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.
