Analysis of the datasets showed that the JMJD6 gene was gained in every human neuroblastoma tissue with 17q gain, and that chromosome 17q/JMJD6 gene was gained in 172 of the total of 209 (82.30%), including 21 of 26 MYCN amplified (80.77%) and 149 of 181 MYCN-non-amplified (82.32%), human neuroblastoma tissues (Fig. 1a, b). The gene discussed is MYCN; the disease is neuroblastoma.
