Clinical relevance of the fusion transcripts distribution pattern in mexican children with acute lymphoblastic leukemia.

Chromosomal translocation-generated fusion genes in childhood acute lymphoblastic leukemia (ALL) are well-known indicators of prognostic outcome. This study was conducted to establish the clinical relevance of the fusion genes distribution pattern in Mexican children with newly diagnosed ALL. Multiplex RT-PCR assays were used to detect 4 commonest fusion transcripts in 261 Mexican children with B-cell precursor ALL aged 1 to 14 years old, comparing differences in the distribution of the patients between molecular subgroups to a common collection of clinical parameters.
