Chromosome 1p36 in migraine with aura
Bibliographic record
Abstract
Migraine with aura (MA) may share some but not all risk factors with other forms of migraine. As common migraine without aura (MO) has been associated with the chromosome 1p36 locus, we tested its involvement in MA by using two-point parametric linkage analysis to analyze 64 multiplex MA families. A logarithm of the odds score of 1.9 was suggestive of chromosome 1p36 linkage to MA. The transmission disequilibrium test analysis was then performed in 79 nuclear families with one MA parent and one MA offspring. We identified the presence of genetic association at chromosome 1p36 with MA (P=0.045, Bonferroni corrected): the locus encoding the 5HT(1D) receptor gene. Although these data suggest that the 1p36 locus may protect against MA, consistent with the role of the 5HT(1D) receptor in migraine treatment with triptan drugs, the study is subject to the limitations associated with studying a small number of affected families. As a result, we contrast evidence suggesting that the chromosome 1p36 locus is strongly MO associated with our finding that 1p36 has a more limited contribution to MA in the families we analyzed. Further work using a genome-wide association study approach in familial typical migraine, consisting of those affected by MO or MA, will serve to further distinguish how and why MA differs from MO.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
