Conversely, STUMPs and LMSs shared 47 CNAs, in particular gain/amplification of the regions containing cancer related genes as PRKDC (8q11.21; eight samples), MLL3 (7q36.1; seven samples), ROCK2 (2p25.1; six samples), CTSB (8p23.1; six samples) and STAT2 (12q13.2; five samples) (Table S1 and Table 3). This evidence concerns the gene ROCK2 and cancer.
