Similarly, Gupta S et al. and Wyvekens N et al. studied TFEB-amplified RCC and TFEB-translocated RCC, respectively, and they found that both types of tumors typically express melanin A and histone enzyme K. The difference was that tumor cells in TFEB-amplified RCC were usually diffusely or patchily positive when tested for TFEB levels [27]. The gene discussed is TFEB; the disease is neoplasm.
