As shown in Figure 2, only the expression of SCN4A (p = 0.049) and SCN7A (p = 0.011) was significantly changed; furthermore, the trends in SCN4A and SCN7A expression in tumour and non-tumour tissues were consistent with the results in the UALCAN database, in which the expression of SCN4A was higher in tumours and SCN7A was lower in tumours. This evidence concerns the gene SCN7A and neoplasm.
