MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] In acute myeloid leukemia, especially in the M2 subtype, the t(8;21)(q22;q22) translocation is one of the most frequent karyotypic abnormalities. The translocation produces a chimeric gene made up of the 5'-region of the RUNX1 (AML1) gene fused to the 3'-region of the CBFA2T1 (MTG8) gene. The chimeric protein is thought to associate with the nuclear corepressor/histone deacetylase complex to block hematopoietic differentiation. The protein encoded by this gene binds to the AML1-MTG8 complex and may be important in promoting leukemogenesis. Several transcript variants are thought to exist for this gene, but the full-length natures of only three have been described. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a null allele are smaller and show reduced numbers of intestinal goblet, Paneth and enteroendocrine cells, small intestine inflammation, and strain dependent postnatal lethality. Homozygotes for a different null allele are infertile due to defects in primordial germ cell maturation. [provided by MGI curators]
