Other genes expressed more highly in PBM versus ABM included genes associated with early B-lymphoid development (DNTT and FLT3), the transcription factor and proto-oncogene (ETV6) that is frequently mutated in hematological malignancies, and genes involved in cell growth, proliferation, and apoptosis (YPEL3 and AKR1C3; Figure S4C). Here, AKR1C3 is linked to hematologic disorder.
