TYRO3 was present in the nucleus in approximately 40% of leiomyosarcoma patient samples that expressed TYRO3, but was not observed in tumor samples from patients with other sarcomas, including dedifferentiated liposarcomas, undifferentiated pleiomorphic sarcomas, and synovial sarcomas [61,62]. This evidence concerns the gene TYRO3 and leiomyosarcoma.
