CPM and dedifferentiated liposarcoma: These studies have also identified a number of genes within 12q13-15, including HOXC13, MDM2, HMGA2, CDK4, and CPM, as being key to the development of DDLPS and WDLPS; a number of additional genomic occurrences, such as the loss of 11q23 and the gain of 6q23 and 1p32, have been defined as genomic abnormalities that are specific to DDLPS6,8,11–17.
