We note that the RBFOX family of proteins includes RBFOX1, RBFOX2, and RBFOX3; however, RBFOX1 and RBFOX3 show the greatest extent of downregulation across different tumours (>60-fold, Fig. 5a, b), whereas RBFOX2 shows comparatively moderate downregulation (~3-fold, Supplementary Fig. 13). This evidence concerns the gene RBFOX3 and neoplasm.
