AbstractBackground and aimMetabolic syndrome (MetS) increases the risk of atherosclerosis and diabetes, but there are no approved predictive markers. This study assessed the role of specific genetic variations in MetS susceptibility and their impact on clinical manifestations.MethodIn this study, a genotype–phenotype assessment was performed for IKZF3 (rs907091), microRNA‐let‐7a‐2 (rs1143770), and lncRNA‐CDKN2B‐AS1 (rs1333045).ResultsAnalyses indicate that while rs907091 and rs1143770 may have potential associations with MetS susceptibility and an increased risk of atherosclerosis and diabetes, there is an observed trend suggesting that the rs1333045 CC genotype may be associated with a decreased risk of MetS. The genotypes and allele frequencies of rs1333045 were significantly different between studied groups (OR = 0.56, 95% CI 0.38–0.81, p = 0.002, and OR = 0.71, 95% CI 0.55–0.92, p = 0.008), with the CC genotype displaying increased levels of HDL. Furthermore, the rs907091 TT genotype was associated with increased triglyceride, cholesterol, and HOMA index in MetS patients. Subjects with the CC genotype for rs1143770 had higher HbA1c and BMI. In silico analyses illustrated that rs907091 C remarkably influences the secondary structure and the target site of a broad spectrum of microRNAs, especially hsa‐miR‐4497. Moreover, rs1333045 creates a binding site for seven different microRNAs.ConclusionFurther studies on other populations may help confirm these SNPs as useful predictive markers in assessing the MetS risk.
