To confirm and extend these original findings, we first established the expression levels of all group 1 and 2 CD1 genes in acute leukemia by interrogating 16 publicly available gene expression datasets from adult and pediatric AML, B-ALL, and T cell acute lymphoblastic leukemia (T-ALL) patients (Supplementary Table 1). Here, CD1A is linked to T-cell acute lymphoblastic leukemia.
