Background and aim: Coronary artery disease (CAD) remains a leading cause of morbidity and mortality globally despite advancements in treatment. Long non-coding RNAs (lncRNAs) play crucial roles in the atherosclerotic process, with ANRIL being one such lncRNA. This study explored the association between ANRIL polymorphisms (rs1333049:C > G, rs564398:T > C, and rs10757274:A > G) and CAD along with CAD risk factors in a Turkish patient group. Methods: The study included 1285 participants, consisting of 736 patients diagnosed with CAD (mean age = 63.3 ± 10.5 years) and 549 non-CAD controls (mean age = 57.52 ± 11.01 years). Genotypes for rs1333049, rs564398, and rs10757274 were determined using qRT-PCR. Results: G allele carriage of both rs1333049 and rs10757274 polymorphisms were associated with higher Gensini score, SYNTAX score, total cholesterol, and triglyceride levels in female CAD patients and non-CAD males. Females with rs564398 CC genotype were more susceptible to CAD (p = 0.02) and severe CAD (p = 0.05). Moreover, the G and T alleles of rs10757274 and rs564398 were more prevalent among hypertensive males. Also, carrying the C allele for rs564398 was associated with a decreased risk for type 2 diabetes mellitus (T2DM) (p = 0.02). Besides, carriers of the rs1333049 C allele for decreased risk for T2DM (p = 0.03) and CAD complexed with T2DM (p = 0.04) in logistic regression analyses. Conclusions: In conclusion, selected ANRIL polymorphisms were associated with CAD presence/severity and CAD risk factors, T2DM, and hypertension. Notably, this study, the largest sample-sized study examining the effects of selected polymorphisms on CAD and its risk factors among Turkish individuals, supported the findings of previous studies conducted on different ethnicities.
