Monarch Disease Ontology id MONDO_0006397 (renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions) is a group of kidney carcinomas characterized by the presence of different translocations involving the chromosome Xp11.2. These translocations result in the creation of gene fusions involving the TFE3 gene. Patients are usually children and young adults. Morphologically, the malignant epithelial cells form papillary patterns. Also known as: TFE3-Rearranged renal cell carcinoma, Xp11.2 translocation-related renal cell carcinoma, renal cell cancer associated with Xp11.2 translocations/TFE3 Gene fusions, tRCC.
