Exceptionally, the TCGA dataset for ovarian cancer (TCGA–OV) showed a reduction in EEF1A2 and EEF1A1 expression compared with GTEx normal tissue (Fig. 4A and B), which could be due to other mutations, sample heterogeneity, normalization techniques or statistical methodologies, sample size, and clinical variations. This evidence concerns the gene EEF1A2 and ovarian cancer.
