| More Details: | Abstract Aims/Introduction Fatty acid desaturase (FADS) genetic polymorphisms are strongly correlated with the risk of dyslipidemia and cardiovascular disease. In this study, we examined the impact of FADS1 and FADS2 genetic variants on plasma lipid status, and assessed interactions between FADS genetic polymorphisms and plasma n‐3/n‐6 fatty acids regarding lipid status within a population of 816 Taiwanese patients with type 2 diabetes. Materials and Methods Selected tag single‐nucleotide polymorphisms (FADS1 rs174546 [T/C]; FADS2 rs174602 [A/G] and rs2072114 [A/G]) were genotyped (n = 816). Results The distribution of genotypes were compared with reports publicly available in the Genome Aggregation Database for East Asian populations (https://gnomad.broadinstitute.org). In the subgroup of patients not taking lipid‐lowering medications (n = 192), we observed that the G allele of FADS2 rs174602 was statistically significantly correlated with lower low‐density lipoprotein cholesterol (LDL‐C) concentrations (P = 0.001), whereas the G allele of rs2072114 was marginally associated with LDL‐C concentrations (P = 0.091). Using a general linear model adjusted for confounding factors, statistically significant interactions (P = 0.016) between single‐nucleotide polymorphisms in rs2072114 and a low alpha‐linolenic acid (18:3n‐3)/linoleic acid (18:2n‐6) ratio; the G allele correlated with lower LDL‐C levels among individuals with a low alpha‐linolenic acid/linoleic acid ratio. Interaction between rs174602 single‐nucleotide polymorphisms and low alpha‐linolenic acid/linoleic acid values on LDL‐C was only marginally significant (P = 0.063). Conclusions Our results show the role of n‐3/n‐6 dietary polyunsaturated fatty acids in modifying the effects of genetic susceptibility on lipoprotein concentrations in patients with type 2 diabetes. Our findings highlight the potential of interventions with dietary polyunsaturated fatty acids regarding developing individualized prevention strategies for type 2 diabetes presenting with co‐occurring dyslipidemia and cardiovascular diseases. |
