As a result of the genetics research into lymphedema, I recently learned about yet another syndrome that expresses itself with primary lymphedema. The condition is called Emberger Syndrome.
Emberger involves acute myeloid leukemia and primary lymphedema. Other complications may include immune abnormalities, and deafness. As we see in the article below it is caused by a mutation in the GATA2 gene. For information on this gene see GATA binding protein 2.

Four reports have been published on an association between acute myeloid leukemia (AML) and primary lymphedema, with or without congenital deafness. We report seven new cases, including one extended family, confirming this entity as a genetic syndrome. The lymphedema typically presents in one or both lower limbs, before the hematological abnormalities, with onset between infancy and puberty and frequently affecting the genitalia. The AML is often preceded by pancytopenia or myelodysplasia with a high incidence of monosomy 7 in the bone marrow (five propositi and two relatives). Associated anomalies included hypotelorism, epicanthic folds, long tapering fingers and/or neck webbing (four patients), recurrent cellulitis in the affected limb (four patients), generalized warts (two patients), and congenital, high frequency sensorineural deafness (one patient). Children with lower limb and genital lymphedema should be screened for hematological abnormalities and immunodeficiency.
