Abstract

The chromosome break points of the t(8;21)(q21.3;q22.12) translocation associated with acute myeloid leukemia disrupt the RUNX1 gene (also known as AML1) and the RUNX1T1 gene (also known as CBFA2T3, MTG8 and ETO) and generate a RUNX1-RUNX1T1 fusion protein. Molecular characterization of the translocation break points in a t(5;8)(q32;q21.3) patient with mild-to-moderate mental retardation and congenital heart disease revealed that one of the break points was within the RUNX1T1 gene. Analysis of RUNX1T1 expression in human embryonic and fetal tissues suggests a role of RUNX1T1 in brain and heart development and support the notion that disruption of the RUNX1T1 gene is associated with the patient's phenotype.
