Abstract
Hegele, Robert A., Henian Cao, Stewart B. Harris, Bernard Zinman, Anthony J. Hanley, and Carol M. Anderson. Genetic variation in LMNA modulates plasma leptin and indices of obesity in aboriginal Canadians. Physiol Genomics 3: 39–44, 2000.—We previously showed that a rare mutation in LMNA, which encodes lamins A and C, underlies autosomal dominant Dunnigan-type familial partial lipodystrophy (FPLD). Because FPLD is an extreme example of genetically disturbed adipocyte differentiation, it is possible that common variation in LMNA is associated with obesity-related phenotypes. We therefore analyzed the relationships between the common LMNA 1908T/C single nucleotide polymorphism (SNP) and plasma leptin and anthropometric indices in 306 nondiabetic Canadian Oji-Cree. We found that subjects with the LMNA 1908T/1908T genotype had significantly higher plasma leptin than the subjects with either the 1908C/1908T or 1908C/1908C genotypes, after adjustment for age and sex. Physical indices of obesity, such as body mass index, percent body fat, and ratio of waist-to-hip circumference, were also higher among Oji-Cree subjects with the LMNA 1908T/1908T genotype than the subjects with either the 1908C/1908T or 1908C/1908C genotypes. The results suggest that common genetic variation in LMNA may be an important determinant of plasma leptin and obesity-related quantitative traits.

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
