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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.1378G>C (p.A460P) alteration is located in exon 9 (coding exon 9) of the CBFA2T3 gene. This alteration results from a G to C substitution at nucleotide position 1378, causing the alanine (A) at amino acid position 460 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
