Selected polymorphisms of VEGF gene in chronic renal failure
Journal Title: Annales Academiae Medicae Silesiensis - Year 2018, Vol 72, Issue
Abstract
INTRODUCTION: Understanding the complex etiopathogenesis of chronic kidney disease (CKD) raises hopes for the development of effective methods for its early diagnosis and effective prevention and treatment. The significance of genetic predisposition in renal damage development has been proven in many studies. The objective of our study was to estimate the connections between selected VEGF polymorphisms and the incidence of chronic renal failure. MATERIALS AND METHODS: 103 families, consisting of both parents and affected offspring with CKD stage below 3, i.e. eGFR below 60 ml/min/1.73 m2, participated our study. The mean age of the children was 15.2 years and mean eGFR 28.9 ml/min/1.73 m2. The main reason for renal damage was interstitial nephropathy (71%) and the second (29%) – chronic glomerulonephritis. 45% of patients were conservatively treated, while others remained on chronic renal replacement therapy. Venous blood samples were collected for DNA isolation. Selected VEGF polymorphisms were genotyped by the TaqMan method. The obtained results were analyzed on the basis of Statistica 10 and Microsoft Office Excel 2003 software using the transmission disequilibrium test (TDT), χ2 test and the Kaplan-Meier estimator. For all the calculations, a p value below 0.05 was adopted as the limit of statistical significance. RESULTS: No differences in the estimated and observed rs699947 or rs1570360 allele transmission between the parents and their affected offspring were found. CONCLUSIONS: No relations between rs699947 and rs1570360 VEGF polymorphisms and the incidence of chronic kidney disease of at least stage 3 were established.
