The exceptions are three genes (NTRK2, EPHB3, and EPB41L2), which are known to play a role in neural systems, and only appear in some of the core modules from the two cancer types of neural origin, gliomas and melanoma, and NSCLC that expresses prominent features of neuroendocrine cells. The gene discussed is NTRK2; the disease is non-small cell lung carcinoma.
