The aim of this study was to investigate the presence of polymorphism rs12917707 in the UMOD gene, rs17319721 in the SHROOM3 gene, rs1800871 and rs3024505 in the IL10 gene, rs1800795 in the IL6 gene, rs3212227 in the IL12B gene, rs11209026 and rs1800896 in the IL23R gene, and rs361525 and rs1800629 in the TNF gene in a group of children from Serbia with GN. Here, IL10 is linked to ganglioneuroma.
