However, when we queried for differentially expressed genes in the limited available normal adjacent versus tumor tissues (Supplementary-Tables 5 and 6), we identified only the chemokine receptors CXCR2, CXCR6, and CX3CR1 to be commonly differentially expressed in normal versus tumor samples for both Black and White patients. The gene discussed is CXCR6; the disease is neoplasm.
