CD84 and acute myeloid leukemia: Importantly, according to PRECOG database analysis (https://precog.stanford.edu/) (27) and KMPlot database analysis (https://kmplot.com/analysis/) (28), elevated CD84 mRNA expression is associated with shorter overall survival in patients with AML (GEO GSE10358, P = 0.01; KMPlot database, P = 0.028) (Supplemental Figure 1, F and G) but this was not observed when The Cancer Genomic Atlas (TCGA) and Beat AML (https://www.cancer.gov/ccg/blog/2019/beataml) genomic data sets were interrogated (29).
