Clinical and Interpretive info

  

An interpretive report will be provided

  

MPL (myeloproliferative leukemia virus oncogene homology) belongs to the hematopoietin superfamily and enables its ligand thrombopoietin to facilitate both global hematopoiesis and megakaryocyte growth and differentiation.
