The genotype GG of single nucleotide polymorphism (SNP) rs1800795 (-174 G>C) in interleukin (IL)-6 promoter has been associated with lower survival of high-risk NB.
Because the rs1800795 SNP [-174 IL-6 (G > C)] has been shown to correlate with production of IL-6, this cytokine may represent a target for development of new therapies in neuroblastoma.
