The majority of the genes in the signature are involved in processes associated with tumor growth such as DNA replication (BUB1, CCNB1, CENPA, ORC6L, RFC4, TK1), cell cycle control (BUB1, CCNB1, MYBL2, ORC6L, PKMYT1, RACGAP1), cellular assembly and organization (BUB1, CCNB1, CENPA, DIAPH3), and ubiquitination (UBE2S). The gene discussed is RACGAP1; the disease is neoplasm.
