Abstract

fetched live from OpenAlex

<b><i>Background:</i></b> A recent genome-wide association study (GWAS) by our group identified 13 loci associated with the plasma triglyceride (TG) response to omega-3 (n-3) fatty acid (FA) supplementation. This study aimed to test whether single-nucleotide polymorphisms (SNPs) within the <i>IQCJ, NXPH1, PHF17</i> and <i>MYB</i> genes are associated with the plasma TG response to an n-3 FA supplementation. <b><i>Methods:</i></b> A total of 208 subjects followed a 6-week n-3 FA supplementation of 5 g/day of fish oil (1.9-2.2 g of eicosapentaenoic acid and 1.1 g of docosahexaenoic acid). Measurements of plasma lipids were made before and after the supplementation. Sixty-seven tagged SNPs were selected to increase the density of markers near GWAS hits. <b><i>Results:</i></b> In a repeated model, independent effects of the genotype and the gene-supplementation interaction were associated with plasma TG. Genotype effects were observed with two SNPs of <i>NXPH1</i>, and gene-diet interactions were observed with ten SNPs of <i>IQCJ</i>, four SNPs of <i>NXPH1</i> and three SNPs of <i>MYB</i>. Positive and negative responders showed different genotype frequencies with nine SNPs of <i>IQCJ</i>, two SNPs of <i>NXPH1</i> and two SNPs of <i>MYB</i>. <b><i>Conclusion:</i></b> Fine mapping in GWAS-associated loci allowed the identification of SNPs partly explaining the large interindividual variability observed in plasma TG levels in response to an n-3 FA supplementation.

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.
