RHOB and cancer: In a TCGA‐based analysis using the lung adenocarcinoma database, no RHOB mutation or deletion was found (Appendix Fig S6A), which confirms previous observations in lung cancer (Sato et al, 2007) and in our laboratory (unpublished data) or in other cancers such as head and neck carcinoma (Adnane et al, 2002) or breast cancer (Fritz et al, 2002).
