The NFATc2 Gene Is Involved in a Novel Cloned Translocation in a Ewing Sarcoma Variant That Couples Its Function in Immunology to Oncology

Abstract
Purpose: Ewing sarcoma is an aggressive sarcoma and is the second most common bone sarcoma in childhood. Disease-specific t(11;22) (∼85-90%), t(21;22) (∼5-10%), or rarer variant translocations with the involvement of chromosome 22 (∼5%) are present. At the gene level, the EWSR1 gene fuses with FLI1, ERG, or other ETS transcription factor family members. Thus far, no Ewing sarcoma has been identified with a fusion to transcription factors other than ETS.
