Background.The polymorphism R229Q is one of the most commonly reported podocin sequence variations among steroid-resistant\nnephrotic syndromes (SRNS).Aimof the Study.We investigated the frequency and risk of this polymorphism among a group of Iraqi\nchildren with SRNS and steroid-sensitive nephrotic syndrome (SSNS). Patients andMethods.Aprospective case control studywhich\nwas conducted in Al-Imamein Al-Kadhimein Medical City, spanning the period from the 1st of April 2015 to 30th of November\n2015. Study sample consisted of 54 children having NS, divided into 2 groups: patients group consisted of 27 children with SRNS,\nand control group involved 27 children with SSNS. Both were screened by real time polymerase chain reaction for R229Q in exon\n5 of NPHS2 gene. Results. Molecular study showed R229Q polymorphism in 96.3% of SRNS and 100% of SSNS. There were no\nphenotypic or histologic characteristics of patients bearing homozygous R229Q polymorphism and the patients with heterozygous\nR229Q polymorphism. Conclusion. Polymorphism R229Q of NPHS2 gene is prevalent in Iraqi children with SRNS and SSNS.\nFurther study needs to be done, for other exons and polymorphism of NPHS2 gene in those patients.
