Genes affected
CBFA2T3 (HGNC:1537): (CBFA2/RUNX1 partner transcriptional co-repressor 3) This gene encodes a member of the myeloid translocation gene family which interact with DNA-bound transcription factors and recruit a range of corepressors to facilitate transcriptional repression. The t(16;21)(q24;q22) translocation is one of the less common karyotypic abnormalities in acute myeloid leukemia. The translocation produces a chimeric gene made up of the 5'-region of the runt-related transcription factor 1 gene fused to the 3'-region of this gene. This gene is also a putative breast tumor suppressor. Alternative splicing results in transcript variants. [provided by RefSeq, Nov 2010]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.1607G>A (p.R536Q) alteration is located in exon 11 (coding exon 11) of the CBFA2T3 gene. This alteration results from a G to A substitution at nucleotide position 1607, causing the arginine (R) at amino acid position 536 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
