The SORT1 risk allele is associated with exaggerated postprandial lipaemia in young adults (383.5)
Bibliographic record
Abstract
Elevations in low‐density lipoproteins (LDL), very‐low density lipoproteins (VLDL) and triglycerides (TG) in the postprandial state have a strong genetic component and recognized atherogenic potential. We sought to determine if there is a difference in postprandial lipaemia following an oral fat tolerance test when stratified by genotype at the SORT1 1p13 locus, the strongest LDL‐cholesterol associated locus identified to date. Thirty, healthy young adults (age=23.57) received a high fat, mixed meal (91 g, 55% kcal from fat). Blood samples drawn at fasting, 2, 4, 8 and 24 hrs postprandial, underwent comprehensive lipoprotein analyses via nuclear magnetic resonance profiling. At fasting, VLDL particles differed based upon SORT1 genotype (TT: 48.81±5.07 nmol/L versus TC/CC: 30.05±2.99 nmol/L, p=0.004). Major, risk allele homozygotes (TT) had significantly elevated area‐under‐the‐curve and mean concentration for VLDL particles, TG and VLDL‐TG (p<0.05). These results indicate increased fasting and postprandial exposure to atherogenic particles in TT homozygotes. This highlights SORT1 as a valuable target for identifying individuals for early, personalized interventions to prevent atherosclerosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
