For example, Miettinen and Rapola [39] found that rhabmyosarcoma and rhabmyosarcoma-like tumors from a wide range of patients exhibited immunoreactivity to NFM protein, while Molenaar and Muntinghe [40] reported that the expression of NCAM and NFM isoforms were widely expressed by skeletal muscle tumors. Here, NCAM1 is linked to skeletal muscle neoplasm.
