Recently, a fusion transcript of CD63–BCAR4 was also reported in a comprehensive genomic study of Chinese NSCLC patients.31 Fusion variants of ERBB3–BCAR4 were detected in two patients, one from a whole-genome-sequencing dataset of Chinese lung adenocarcinoma patients and another one from lung adenocarcinoma project of The Cancer Genome Atlas consortium (TCGA–LUAD) as demonstrated in Fig. 1e. Here, BCAR4 is linked to non-small cell lung carcinoma.
