This study, for the first time, sought to investigate whether the interaction between the GRS consists of three SNPs (CAV-1, CRY-1, MC4R) and fat intake is associated with inflammatory markers among Iranian overweight and obese women. This cross-sectional study was conducted with 246 overweight and obese women, aged 18-48 years. Three SNPs, including CAV-1 rs3807992, CRY-1 rs2287161, and MC4R rs17782313, were genotyped using PCR-RFLP to calculate the genetic risk score (GRS) for each participant. Dietary fat intake was measured using a validated semi-quantitative food frequency questionnaire (FFQ). C-reactive protein (CRP), interleukin-1β (IL-1β), transforming growth factor-β (TGF-β), monocyte chemoattractant protein-1 (MCP-1), plasminogen activator inhibitor-1 (PAI-1), and Galectin-3 (Gal-3) were assessed as the primary outcomes of the study. After controlling for confounding variables, a significant interaction between high total fat intake and high GRS, compared to the reference group, was found for TGF-β level ( Consuming different types of fats can influence the interaction between GRS and inflammatory markers, suggesting further research is needed to fully understand this relationship.
