In our study, the MYB-NFIB fusion gene appeared in 8 of 15 (53.3%) ACC tissues, and the MYBL1-NFIB fusion gene appeared in 3 of 15 (20%) ACC tissues; the rates were slightly higher than those in the literature [45% (9/20) and 15% (3/20), respectively, as determined by RNA-seq using formalin-fixed, paraffin-embedded (FFPE) tissues] (Shibata et al., 2021). This evidence concerns the gene NFIB and adrenal cortex carcinoma.
