PTPRJ and acute promyelocytic leukemia: Overexpression of CD339/JAG1 in APL was the only consistent finding in the two datasets, in line with previous reports including both gene expression data from RNA-Seq and microarray analyses [27] or flow cytometry studies [28] Of note, differential expression in APL and other AML subtypes cannot be deduced from these earlier studies for all CD genes identified by our calculations, such as CD84 [29], CD88 [30], CD148 [23,31], CD210A/IL10RA, and CD227 [32,33].
