CDKN2A and sarcoma: The top marker for differentiation between sarcoma cluster 3, which is mainly composed of PLS samples, and sarcoma cluster 4, which is composed of MFS and UPS samples, was a CpG site located in the gene body of CDKN2A. Furthermore, we identified a correlation between gene expression and DNA methylation of this CpG site in PLS and DDLS compared to non-neoplastic fat tissue.
