Numerous hematological diseases, in particular leukemias, can be treated successfully with allogeneic bone marrow transplantation (allo-BMT). Highly polymorphic microsatellite markers and X, Y-chromosome-specific sequences provide useful genetic markers for detection of complete or mixed chimerism in patients after allo-BMT. Chimerism can be monitored successfully using polymerase chain reaction technique (PCR) and cytogenetic analysis, especially fluorescent in situ hybridization (FISH). It is still unclear whether individuals with mixed chimerism after bone marrow transplantation have an increased risk of developing leukemic relapse or graft rejection. Molecular study of cellular chimerism can also be used for quantitative assessment of the amount of donor's cells in a recipient after bone marrow transplantation and for monitoring of minimal residual disease (MRD) or disease relapse. We report application of three different DNA-typing techniques: automated DNA sizing technology, fluorescent in situ hybridization and also Y-specific DNA probing for analysis of post-BMT chimerism in a case of sex-mismatched bone marrow transplantation. Key words: allo-BMT, chimerism, FISH, PCR.
