Among these, we noticed genes that suggest a neural differentiation of D842V tumors such as DRD1, SSTR1, NPBWR1, and CCK. Moreover, it is known that GIST express somatostatin receptors [24] and that SSTR1 was widely reported [25] as expressed in the better differentiated gastroenteropancreatic neuroendocrine tumors and associated with a good prognosis. The gene discussed is NPBWR1; the disease is gastrointestinal stromal tumor.
