Despite a lack of studies analyzing the association between obesity risk and FADS or ELOVL polymorphisms, some authors have observed that minor alleles of rs174547 (FADS1) confer a higher risk of obesity-related conditions, such as increased triglyceride levels and decreased high-density lipoprotein cholesterol concentrations [24–26], as well as an increased risk of coronary disease [26, 27]. This evidence concerns the gene FADS1 and obesity disorder.
