Figure 2.
Comparison of genetic alterations between ESCC and EAC. The frequency of alteration of the genes in red presented in Fig. 1 was compared between ESCC and EAC according to the data from cBioPortal. SF: similar frequency. If the frequency of alteration in a gene is greater than 2-fold (≥2) in ESCC compared to that in EAC, the gene is assigned to ‘ESCC > EAC’. If the frequency of alteration in a gene is greater than 2-fold (≥2) in EAC compared to that in ESCC, the gene is assigned to ‘ESCC < EAC’. If the difference in the frequency of alteration in a gene is less than 2-fold, the gene was considered as ‘similar frequency’ in both ESCC and EAC. (A) Frequency of mutations. (B) Frequency of copy number variations.
