The Association of Polyunsaturated Fatty Acid δ-5-Desaturase Activity with Risk Factors for Type 2 Diabetes Is Dependent on Plasma ApoB-Lipoproteins in Overweight and Obese Adults.
In the population studied, there was a strong association in the erythrocytes fatty acid composition, D5D and D6D activities and other metabolic risk factors between non-T2D and T2D patients.
Among single genetic variants consistently associated with diabetes-related metabolites, two (rs174550 (FADS1), rs3204953 (REV3L)) were significantly associated with type 2 diabetes in large-scale meta-analysis for type 2 diabetes.
Importantly, among four single nucleotide polymorphisms (rs174545, rs2072114, rs174602 and rs174616) in the FADS1-FADS2 gene cluster, only minor allele (T) of rs174616 was associated with decreased risk of T2DM in both codominant and dominant models after adjustment for age, gender and BMI.
