CABLES1 and synovial sarcoma: Additionally, we identified a number of druggable genes that may interact with known SS-related genes, despite they themselves are lacking of known associations with FSS, including CDK3 (which interacts with CABLES1), TGFBR1 (which interacts with TGFB3), PDE9A (which interacts with HPRT1), TEK (which interacts with PIK3R1), and KLK7 (which interacts with CDSN).
