More recently, gene expression profile analyses revealed a prognostic value of genes involved in FA (RMI1, FANCI, and FANCA), NER (PCNA, RPA3, LIG3, POLD3, ERCC4, POMD1, ERCC1, and ERCC5), NHEJ [WHSC1 (MMSET), RIF1, XRCC5 (Ku80), PNKP, and POLL], MMR (EXO1 and MSH2), and HRR (EXO1, BLM, RPA3, RAD51, MRE11A, and ATM) pathways in MM (Kassambara et al., 2014). The gene discussed is PCNA; the disease is Miyoshi myopathy.
