RAC2 is a GTPase that is exclusively expressed in hematopoietic cells. Animal models have suggested important roles for RAC2 in the biology of different cell types, such as neutrophils and lymphocytes. Primary immunodeficiencies represent “experimentum naturae” and offer priceless insight on the function of the human immune system. Mutations in RAC2 have been identified in a small number of patients giving rise to different forms of primary immunodeficiencies ranging from granulocyte defects caused by dominant negative mutations to combined immunodeficiency due to dominant activating mutations. This review will focus on the clinical and immunologic phenotype of patients with germline mutations in RAC2.

Abstract
RAC2 is a GTPase that is exclusively expressed in hematopoietic cells. Animal models have suggested important roles for RAC2 in the biology of different cell types, such as neutrophils and lymphocytes. Primary immunodeficiencies represent “experimentum naturae” and offer priceless insight on the function of the human immune system. Mutations in RAC2 have been identified in a small number of patients giving rise to different forms of primary immunodeficiencies ranging from granulocyte defects caused by dominant negative mutations to combined immunodeficiency due to dominant activating mutations. This review will focus on the clinical and immunologic phenotype of patients with germline mutations in RAC2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
