Particularly, we observed that expression range was wide for HLA-G in all the cohorts studied, especially in SKCM (2.02–12.8), while for HIF1A, the distribution was near to the median value such as in SKCM (9.25–12.9) suggesting a great variability in HLA-G expression for each tumor type of TCGA cohort (Figure 2). Here, HIF1A is linked to neoplasm.
