hSNF5 /INI1 mutation analysis in acute myeloid leukemia.
Previous studies indicated that region 11.2 of the long arm of chromosome 22 (22q11.2) might be a locus encoding a tumor suppressor gene, since its deletion is a recurrent genetic characteristic of aggressive pediatric cancer. This region is found in the human immunodeficiency virus integrase interactor 1 (hSNF5/INI1) gene. To investigate whether the hSNF5/INI1 gene is involved in leukemogenesis, mutation analysis of the hSNF5/INI1 gene was performed in the present study using 5 hematopoietic cell lines, acute myeloid leukemia (AML) specimen and normal control. We found two single nucleotide polymorphisms at the hSNF5/INI1 gene in exon 4 and exon 9. The results of this study suggest that the hSNF5/INI1 gene does not play an important role in the leukemogenesis of AML.
