LMO2 and acute lymphoblastic leukemia: The HHEX-positive T-ALLs showed statistically significant, concordant expression of LYL1, MYCN, LMO2, BCL2, and MEF2C. We confirmed the concordant expression of HHEX and LMO2 by qRT-PCR analysis on an independent set of 23 primary T-ALL samples (Figure S3 in File S1).
