SXN29 expression was positively correlated with resting memory CD4 T cells in PRAD, KIRC, DLBC, UCEC, BRCA, LUAD, TGCT, kidney renal papillary cell carcinoma (KIRP), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), HNSC, LGG and LUSC but negatively correlated with resting memory CD4 T cells in KIRP. This evidence concerns the gene CD4 and testicular germ cell tumor.
