Specifically, polymorphisms such as rs3998860 G>A and rs12781492 A>C in the TET1 gene [18], rs10007915 G>C and rs7670522 A>C in the TET2 gene [19], rs828867 G>A in the TET3 gene [20], and rs13181449 C>T in the NSUN2 gene [21] have been identified as closely linked to neuroblastoma susceptibility. This evidence concerns the gene TET1 and neuroblastoma.
