ETV6 is a transcriptional repressor and is frequently involved in translocations with a variety of different partner genes in a range of hematologic malignancies. Mutations of ETV6 have been described in <5% of myelodysplastic syndromes and appear to be more frequent (ie, 10-24% of cases) in early T cell precursor type (immature) acute lymphoblastic leukemias. These mutations occur throughout the gene and typically correspond to loss of function mutations (nonsense and frameshift mutations). ETV6 mutations may occasionally occur in a homozygous/hemizygous manner and tend to occur with mutations in NOTCH1. In MDS, ETV6 mutations have been independently associated with an adverse prognosis.
