NCF1 and acute myeloid leukemia: For human p47phox-deficient chronic granulomatous disease (CGD) vector testing we generated a cellular model using clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 to introduce a GT-dinucleotide deletion (ΔGT) mutation in p47phox encoding NCF1 gene in the human acute myeloid leukemia PLB-985 cell line.
