The aim of the study: To investigate the correlation between NFKB1 gene expression and NFKB1 (rs28362491) SNP with glycemic profile in Iraqi patients with diabetic nephropathy (T2DN). Materials and methods: For this study, 150 volunteers were split into three groups: 50 in the control group, 50 in the T2DM group, and 50 in the T2DN group. According to the kit&amp;#39;s instructions, spectrophotometric analysis was used to determine the HbA1c (%) and FBG (mg/dl), blood urea (UR) and creatinine (CR) (mg/dl) parameters. The ELIAS kit was used to determine the fasting insulin (&amp;micro;u/ml). RT-qPCR was used for estimation of NFKB1 gene expression. Using specific primer sequences and the polymerase chain reaction method known as restriction fragment length polymorphism (PCR-RFLP), the NFKB1 (rs28362491) SNP was evaluated. Results: When compared to controls, the T2DM and T2DN groups&amp;#39; HbA1c%, FBG (mg/dl), INS (&amp;micro;u/ml), and HOMA-IR% indices of glycemic control were significantly higher (P-value&amp;lt;0.05), highest insulin levels, blood urea, and serum creatinine levels (P-value&amp;lt;0.05). For NFKB1 (rs28362491) SNP, the I/I genotype was present in 11.0% of the Control group, 21.3% of the T2DM group, and 25.8% of the T2DNP group. The p-value for this genotype was &amp;lt;0.001, indicating significant differences in its distribution across the groups. The results of this study revealed that there is a significant difference (P&amp;lt;0.001) in AFC (Average Fold Change) of NFKB1 gene expression were (1.0197&amp;plusmn;0.7), (4.448&amp;plusmn;1.08), and (8.704&amp;plusmn;2.14) in control, T2DM, and T2DN, respectively. Conclusion: Differed expression of NFKB1 between the control group and T2DN&amp;ensp;patients indicates functional involvement of NF-&amp;kappa;B signaling in the development of DN. These results suggest that the regulatory role of NFKB1 expression and the associated&amp;ensp;effect on inflammation and renal function of T2DM need to be proven with further studies. Although this gene might serve as a potential biomarker&amp;ensp;prospect in the future, larger-scale studies are necessary for the verification of predictive susceptibility or guiding therapeutic treatments</p></abstract><trans-abstract xml:lang="en"><p>Background: Diabetic nephropathy is a microvascular complication that can occur in people type 2 diabetes nephropathy (T2DN).
