Aneuploidy in neuroblastoma tumors is not associated with inactivating point mutations in the STAG2 gene.

• Chromosomal instability is a hallmark of human cancer caused by errors in mitotic control and chromosome segregation. STAG2 encodes a subunit of the cohesion complex that participates in mitotic chromatid separation and was recently found to show low expression and inactivating mutations in Ewing's sarcoma, melanoma and glioblastoma.In the childhood tumor neuroblastoma (NB) segmental chromosomal alterations are associated with poor prognosis whereas tumors displaying whole chromosome gains and losses have a much better prognosis.
