Study on ALL-1 gene alterations in Indian childhood acute leukemias: non-isotopic Southern blotting and molecular cytogenetics.
We carried out this study to detect ALL-1 gene alterations in Indian childhood leukemias (n-84) using non-radioactive Southern blotting and FISH techniques. 18 (21.4%) patients showed altered ALL-1 gene. All 18 patients with altered ALL-1 gene did not have high WBC count and or typical CD10-/19+ phenotype. 4/18 were infants, while 14 were of 1-12 years of age. 13/18 children were boys. 14/18 expired within 1 year. Karyotyping detected abnormal chromosome 11 only in 4/43 patients and Classical t(4:11) in one AML patient but combination of Painting FISH and LS-FISH confirmed ALL-1 gene alteration in 17/18 cases. In addition, FISH identified nine translocations and multiple copies of ALL-1 gene in three cases which conventional cytogenetics had failed to detect. Our result indicates that a combination of Southern blotting, cytogenetic and FISH techniques are useful to identify ALL-1 gene alterations in childhood leukemias.
