To understand the mechanism by which PRKCQ‐AS1 is overexpressed in MYCN‐nonamplified neuroblastoma, we first examined whether there was PRKCQ‐AS1 copy number variation in human neuroblastoma tissues using the publicly available single nucleotide polymorphisms (SNP) array dataset which were generated by the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) initiative (https://target‐data.nci.nih.gov/, last accessed June 12, 2013). The gene discussed is MYCN; the disease is neuroblastoma.
