Gene Overview
The RUNX1T1 gene is a member of the human myeloid translocation genes (MTGs). The nuclear MTGs can mediate the formation of complex protein networks among nuclear corepressors (for example Sin3a, N-CoR, SMRT), chromatin-modifying enzymes (for example histone deacetylases), and DNA-binding transcription factors. Repression at target genes by MTG protein complexes is probably required for gene regulation during development and differentiation. Alterations in these genes can disrupt gene regulatory protein networks and can cause of cancers and neurodegeneration [8] The translocation t(8;21)(q22;q22.1);_RUNX1-RUNX1T1 produces a chimeric gene made up of the 5'-region of the runt-related transcription factor 1 (RUNX1) gene fused to the 3'-region of the RUNX1T1 gene. The chimeric protein is thought to associate with the nuclear corepressor/histone deacetylase complex to block hematopoietic differentiation.
Common Alteration Types
The t(8;21)(q22;q22) (RUNXT1, RUNX1) translocation is one of the most frequent karyotypic abnormalities in acute myeloid leukemia with a reported incidence of 7% [5,7]
