Additionally, to determine whether high levels of PRKCQ‐AS1 and MSI2 expression in human neuroblastoma tissues were independent prognostic markers in patients, multivariable COX regression analysis of PRKCQ‐AS1 or MSI2 expression and well‐established neuroblastoma risk factors such as age at the time of diagnosis (> or ≤ 18 months), advanced disease stage (stage 3 and 4) and MYCN gene amplification status was performed. The gene discussed is MYCN; the disease is neuroblastoma.
