KEAP1 and head and neck cancer: In addition to lung cancers, laryngeal squamous carcinoma (13% in [61]), esophageal squamous cancer (ESC, 22% in [60], 11.4% in [61]), head and neck cancers (25% in [54]), skin (1/17 case in [61]), and oral cancer cell lines had somatic changes in NRF2. In contrast to wide-spread KEAP1 mutations, mutations in NRF2 were clustered in DLG/ETGE motifs of the Neh2 domain, which are critical in the “hinge and latch” model of KEAP1 binding [12].
