K. Saitoh et al., TRANSLOCATION (8-12-21)(Q22.1-Q24.1-Q22.1) - A NEW MASKED TYPE OF T(8-21)(Q22-Q22) IN A PATIENT WITH ACUTE MYELOID-LEUKEMIA, Cancer genetics and cytogenetics, 96(2), 1997, pp. 111-114
The translocation t(8; 21)(q22; q22) is found in 40% of cases of acute
myeloid leukemia (AML) designated as the subtype M2 in the French-Ame
rican-British (FAB) classification. The 8; 21 translocation is clinica
lly of interest because patients with this subtype have a good prognos
is. We describe a masked type of the translocation, t(8; 12; 21)(q22.1
; q24.1; q22.1). The translocation was first interpreted as t(8; 12)(q
22; q24) based on cytogenetics, but was reevaluated as a result of Sou
thern blot and fluorescence in situ hybridization (FISH) analyses. (C)
