Abstract


Background: The highly polymorphic gene encoding human renalase (RNLS) is a 311,000 bp gene located on chromosome 10.

Aim: This study aimed at studying the possible association of the two RNLS gene polymorphisms rs2576178 and rs10887800 with chronic kidney disease in general or specifically with hypertensive nephropathy in Egyptian end stage renal disease (ESRD) patients on maintenance hemodialysis.

Subjects and method: This case control study was conducted on two hundred and eighty one individuals, divided equally into two groups; an end stage renal disease patients on maintenance hemodialysis with/without hypertension and healthy matching individuals as a control group. Full clinical examination, Biochemical analysis and Molecular genetic testing were performed to detect single nucleotide polymorphism using restriction fraction length polymorphism (RFLP) for RNLS rs2576178 and rs1088780.

Results: The results of this study demonstrated that the risk of developing ESRD was increased among carriers of AA genotype for the rs10887800 (3.05 times) p = 0.001, OR = 3.05, CI95% (1.558–5.971) and GG genotype for the rs2576178 p = 0.047, OR = 1.949, CI95% (1.028–3.694).

Conclusion: Our study revealed that the risk of developing end stage renal diseases was increased among carriers of AA genotype for the rs10887800 polymorphism and GG genotype for the rs2576178 polymorphism.
