We studied the expression of nine antigens in our B-ALL MRD panel of leukemic blast cell population CD10, CD45, CD20, TdT, CD34, CD19, CD66, CD13, CD33, and three antigens in benign (mature benign B lymphocytes) cell population CD45, CD19, and CD20. The gene discussed is DNTT; the disease is acute lymphoblastic leukemia.
