Using Barretina Sarcoma’s datasets, MCM3 was found to be overexpressed in pleomorphic liposarcoma (fold change = 2.316), myxoid/round cell liposarcoma (fold change = 2.769), myxofibrosarcoma (fold change = 2.122) and leiomyosarcoma (fold change = 2.212) when compared with normal samples. The gene discussed is MCM3; the disease is round cell liposarcoma.
