Our gene expression analysis concurs with previous reports, where overexpression of CD74, CTLA-4, HLA-C, CD79A, IRF5 and LAG3 has been associated with AML and other types of cancer, indicating their potential participation in tumour development, either as tumour initiators or as immunological checkpoint modulators that allow malignant progression [76,77,90–95]. This evidence concerns the gene CTLA4 and neoplasm.
