In addition, other tumor suppressors such as BRCA1 associated deubiquitinase 1 (BAP1), fumarate hydratase (FH), lactamase beta (LACTB), kelch like ECH associated protein 1 (KEAP1) and lysine methyltransferase 2B (KMT2B) have been shown to exert their tumor-inhibitory functions by, at least partially, inducing ferroptosis in tumor cells [4, 6, 7]. The gene discussed is KMT2B; the disease is neoplasm.
