RNF168 and carcinoma of esophagus: Through the survival analysis from TCGA database, we observe that RNF168 gene amplification is correlated with poor overall survival in oesophageal cancer patients (http://www.cbioportal.org/study?id=esca_tcga#summary), which may indicate the involvement of RNF168 in oesophageal cancer progression (Figure 1D).
