Clinics and Pathology

Disease Acute myeloid leukaemia (AML).
Phenotype / cell stem origin AML M4 according to immunophenotyping vs M1 according to cytology.
Epidemiology Found in one case of AML in a 46 years old female Duhoux et al., 2012).
Clinics (
Cytology Leukemic infiltrate of myeloid origin (blasts I and II); high proportion of myeloid blast cells and restricted percentage of monocytes.
Prognosis The patient died 12 months after diagnosis.


Cytogenetics Morphological The t(1;12)(p36;p13.2) was the sole anomaly.
  Left: FISH using the LSI® ETV6 probe : the probe is split between the der(1) and the der(12. Right: FISH using specific probes for PRDM16 (RP5-907A6 and RP1-163G9): the RP1-163G9 probe is split between the der(1) and the der(12), the RP5-907A6 probe is translocated to the der(12)PROBES RP5-907A6 (FITC), RP1-163G9 (Cy3) and LSI® ETV6

Genes involved and Proteins

Gene NamePRDM16 (PR domain containing 16)
Location 1p36.32
Dna / Rna 11 splice variants
Protein 1276 amino acids and smaller proteins. Contains a N-term PR domain; 7 Zinc fingers, a proline-rich domain, and 3 Zinc fingers in the C-term. Binds DNA. Transcription activator; PRDM16 has an intrinsic histone methyltransferase activity. PRDM16 forms a transcriptional complex with CEBPB. PRDM16 plays a downstream regulatory role in mediating TGFB signaling (Bjork et al., 2010). PRDM16 induces brown fat determination and differentiation. PRDM16 is expressed selectively in the earliest stem and progenitor hematopoietic cells, and is required for the maintenance of the hematopoietic stem cell pool during development. PRDM16 is also required for survival, cell-cycle regulation and self-renewal in neural stem cells (Chuikov et al., 2010; Kajimura et al., 2010; Aguilo et al., 2011; Chi and Cohen, 2016).
Gene NameETV6 (ets variant 6)
Location 12p13.2
Protein 452 amino acids. The ETV6 protein contains from N-term to C-Term a HLH (helix-loop-helix, aa 40-124) domain (also referred to as the pointed or sterile alpha motif domain), responsible for hetero- and homodimerization, an internal domain, involved in the recruitment of a repression complex including NCOR1 (17p12), NCOR2 (12q24.31), SIN3A (15q24.2), and SIN3B (19p13.11), and an ETS domain (aa 339-420), responsible for sequence specific DNA-binding and protein-protein interaction (De Braekeleer et al., 2014).

  Schematic representation of the putative ETV6-PRDM16 fusion protein, PRD = prolin-rich domain, DBD1 = DNA-binding domain 1, PRR = prolin-rich domain, RD = repressor domain, DBD2 = DNA-binding domain 2, AD = acidic domain.
Description ETV6 exon 4 is fused to PRDM16 exon 2.
Detection PCR, FISH.
