In line with the activation of the abovementioned RTKs and downstream pathways, SRC and other SRC family kinases (SFKs), which are non-receptor tyrosine kinases cooperatively interacting with RTKs and transducing their signals to downstream effectors [25,26,27,28,29,30], are also frequently hyperactivated in MM [31,32]. Here, NTRK1 is linked to Miyoshi myopathy.
