OMA1 and undifferentiated pleomorphic sarcoma: Correlations were found with the pathological subtype and the tumor site, with more leiomyosarcomas (LMS) and less undifferentiated pleomorphic sarcomas (UPS) among “OMA1-high” tumors than among “OMA1-low” tumors (P = 6.87 × 10−6) and more LMS and less liposarcomas and myxofibrosarcomas among “OPA1-high” tumors than among “OPA1-low” tumors (P = 9.25 × 10−8).
