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]

The c.1934C>G (p.P645R) alteration is located in exon 12 (coding exon 12) of the CBFA2T3 gene. This alteration results from a C to G substitution at nucleotide position 1934, causing the proline (P) at amino acid position 645 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
