Genes involved and Proteins

Gene NameETV6 (ets variant 6)
Location 12p13.2
Protein 53 and 57 kDa; contains, from N-term to C- term, an helix-loop-helix (HLH) domain (or "sterile alpha domain" SAM) responsible of dimerization, and a sequence specific DNA-binding domain (ETS domain); binds to 5' CCGGAAGT 3'; ETV6 is a member of the ETS family of transcription factors; transcriptional repressor.
Gene NameIGH (Immunoglobulin Heavy)
Location 14q32.33

To be noted
