CRLF2 and acute lymphoblastic leukemia: RNAseq results were evaluated, and molecular abnormalities were found in six patients; reversed molecular abnormalities were found in three patients (CREBBP, TP53, and P2RY-CRLF2), and unreported genetic abnormalities in B-ALL, such as TPM4-KLF2 or NR3C1-CDC42 transcript, were also detected (available in the Supplementary material).
