Angiotensin Converting Enzyme Gene Polymorphism in Children With Idiopathic Nephrotic Syndrome
Aims This study was conducted to examine the association between the ACE insertion/deletion (I/D) genotype distribution in children with idiopathic nephrotic syndrome and the response to steroid therapy.
Patients and Methods The patients with idiopathic nephrotic syndrome were divided into 2 groups according to their clinical response to steroid: SS group including infrequent and frequent relapsers and non-SS group including steroid resistant (SR) and steroid dependent (SD) patients. Children without previous renal diseases and negative proteinuria were enrolled as control group in genetic study. The genotypes for ACE gene I/D polymorphism including DD, ID and II were analyzed by the newly developed automatic denaturing high performance liquid chromatography system (DHPLC).
