In this study, we used Affymetrix Human Exon 1.0 ST Array (HuEx) to measure exon expression levels in 47 neuroblastoma samples of different clinical stages and molecular subtypes including stage 1 with normal MYCN copy number (1-), stage 4 with MYCN amplification (4+) or normal MYCN copy number (4-). Here, MYCN is linked to neuroblastoma.
