  Objective: The uromodulin, a glycoprotein, expressed and secreted by epithelial kidney cells lining the thick ascending limb of the Henle’s loop. It is encoded by the UMOD gene in humans. Our objective was to analyze single nucleotide polymorphisms (SNPs) in the UMOD promoter region in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD).Methods: The blood samples were collected from 100 patients with CKD (50) and ESRD (50), who admitted at Merjan Teaching Hospital in Babylon Province, Iraq (February-July 2016). In addition, 50 blood samples of healthy control. The SNPs of UMOD promoter region was investigated using single-strand conformation polymorphism-polymerase chain polymorphisms (SSCP-PCR) and DNA sequencing techniques.Results: UOMD promoter region polymorphisms using PCR-SSCP and sequencing DNA appeared three different conformational haplotypes, including A\G 49 haplotype (5 bands), A\G 49 and C\A 247 haplotype (5 bands), and C\G 45 and A\G 49 haplotype (6 bands) distributed among CKD and ESRD cases, due to the presence of three SNPs. There was no association between band numbers of PCR-SSCP with ESRD and CKD compared with a control group.Conclusion: SSCP-PCR is a good screening method to detect genetic variations in an uromodulin promoter region.
