SLAMF6 and neoplasm: As demonstrated in Fig. 8, there was no difference in the expression level of ENG in tumor and normal tissue adjacent tumors, and the expression of FCER1G was lower in tumor tissue, PSEN1 was higher in tumor tissue, and SLAMF6 was lower in tumor tissue, with Fisher’s precision probability test results at (p = 0.084, p < 0.001, p < 0.001, and p < 0.001), respectively.
