The exoDNA of NB patients carries specific gene mutations unique to NB, including mutations in well-known oncogenes and tumor suppressor genes such as ALK, CHD5, SHANK2, PHOX2B, TERT, FGFR1, and BRAF [105], which aids in distinguishing NB and separating it from other forms of cancer. The gene discussed is CHD5; the disease is neuroblastoma.
