TY - JOUR AB - Diabetic nephropathy (DN) is a major risk factor for end‑stage renal disease (ESRD). MicroRNAs (miRNAs/miRs) and their variants may be implicated in health and disease, including DN. The present study aimed to investigate the association of the miRNA‑499a gene (MIR499A) A/G seed region variant (rs3746444) with DN‑associated ESRD susceptibility in patients with diabetes mellitus, and to determine whether there was an association between the different genotypes and the patients' laboratory and clinical data. A case‑control pilot study was conducted on 180 adult patients with type 2 diabetes mellitus. A total of 90 patients with ESRD on regular hemodialysis were considered as the cases, and 90 age‑, sex‑ and ethnicity‑matched diabetic patients with normo‑albuminuria were considered as the controls. MIR499A genotyping was performed using a TaqMan Real‑Time allele discrimination assay. Results demonstrated that the MIR499A rs3746444*G variant conferred susceptibility to the development of ESRD under co‑dominant [(odds ratio (95% confidence interval): 2.49 (1.41‑3.89) and 2.41 (1.61‑6.68) for heterozygous and homozygous comparison, respectively], dominant [2.30 (1.18‑3.90)] and allelic [1.82 (1.17‑2.83)] models. Different genotypes of the specified variant did not exhibit significant associations with the clinic‑laboratory data of the studied patients or the circulating miR‑499a plasma levels. In conclusion, results of the present study suggested that MIR499A rs3746444 may be a susceptibility variant for DN‑associated ESRD in the study population. However, larger sample size studies with different ethnicities are warranted to verify these findings.
