NF1 and neoplasm: Taking a closer view of the MPNST region, SP‐01's methylome profile matched that of melanoma (like STS‐26T, which was recently reclassified from an MPNST to a melanoma cell line [38]), tumor NF1‐08 clustered with the classic MPNST group (as for ST88‐14 and S462 cell lines), and NF1‐09 clustered in the rather catchall MPNST‐like sarcoma group (Fig. 1D, Table 1).
