MYCN and neuroblastoma: The aim of this study was to analyse genetic alterations determined by array CGH in MYCN-non-amplified localised unresectable/disseminated NB of infants included in the prospective European INES99.1, INES99.2 and INES99.3 protocols (De Bernardi et al, 2009; Rubie et al, 2011) and to study the impact of the genomic profile on clinical characteristics and outcome in this population.
