TGM2 expression in 415 RCC patients ranged from 874.8–169,970.5 RPKM (mean ± SD: 12,576.4 ± 11,671.6), see Figure 1B. Based on the highest expression in normal tissue (10,000 RPKM), subjects were categorized as follows: a normal expression group (n = 219), which had expression levels <10,000 (mean ± SD: 6746.9 ± 2198.2) and an over-expression group (n = 196), which had expression levels >10,000 (mean ± SD: 19,089.9 ± 14,248.1), see Figure 1B. This evidence concerns the gene TGM2 and renal cell carcinoma.
