EEF1A2 and RPN2 are both located in 20q, and EEF1A2 has been suggested to be an oncogene and a diagnostic marker in various cancers [33], but has to our knowledge not previously been linked to sarcomas, whereas RPN2 has been shown to confer drug resistance in breast cancer [34]. The gene discussed is EEF1A2; the disease is breast carcinoma.
