Abstract
Fenofibrate is a peroxisome proliferator-activated receptor alpha (PPARalpha) agonist which regulates the transcription of genes encoding proteins involved in triglyceride (TG)-rich lipoproteins and lipoprotein lipase (LPL) metabolism. The aim of the present study was to investigate the relation between TG-related parameters considered in different clinical guidelines used in industrialized countries for the management of lipid disorders (namely fasting plasma TG, high density-lipoprotein cholesterol (HDL-C), non-HDL-C concentrations and total-C/HDL-C ratio) and the presence of LPL-null (P207L), LPL-defective (D9N), PPARalpha -L162V, apolipoprotein (apo) E and PPARgamma-P12A gene mutations, in a sample of 292 hypertriglyceridemic subjects treated with fenofibrate for 3 months. Although fenofibrate induced a decrease in plasma TG level and an increase in HDL-C level in all studied genotypes, mutation-specific differences were observed. After adjustment for age, gender, body mass index and the presence of apo E2 genotype, the LPL-P207L mutation was associated with residual post-treatment hypertriglyceridemia [TG > 2.0 mmol/l, odds ratio (OR) = 3.07, P = 0.005] and total-C/HDL-C ratio > 5 (OR = 2.68; P = 0.03). This effect was significantly related to higher plasma TG concentrations at baseline among carriers of a LPL-null mutation. Compared to apo E3 and E4 variants, the apo E2 allele was associated with a better response to fenofibrate on all lipid parameter, especially among PPARalpha -L162V carriers, whereas the simultaneous presence of apo E2 and PPARalpha -L162V tended to improve fenofibrate response among LPL-P207L heterozygotes. Finally, the LPL-D9N and PPARgamma -P12A mutations did not affect fenofibrate lipid-lowering action. This study suggests that frequent genetic variations in genes encoding proteins involved in TG-rich lipoprotein metabolism could modulate the response to fenofibrate treatment, as defined in clinical guidelines.

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
