The majority of neuroblastoma patients can be classified into three distinct genomic types [71]: type A tumors with only numerical changes of whole chromosomes, but without any detectable structural rearrangement; type B tumors characterized by the presence of only partial chromosome imbalances (excluding MYCN amplification) in the absence of any numerical chromosomal aberrations; and type C tumors that harbor MYCN amplification without numerical chromosomal aberrations. Here, MYCN is linked to neuroblastoma.
