This article is dedicated to one of the auto-respiratory syndromes – adenosine deaminase deficiency 2 (deficiency of adenosine deaminase 2 – DADA2) in the 12-year-old. This rare disease is caused by mutations in the ADA2 gene (CECR1), that encodes the ADA2 protein. Clinical manifestations of DADA2 are very diverse and usually include systemic inflammatory reaction in the form of fever attacts, vasculopathy in the form of livedo reticulum, polyarteritis nodosa, ischemic and/or hemorrhagic strokes, as well as signs of immunodeficiency with hypogammaglobulinemia and bone marrow failure. Complex pathogenetic mechanisms, variety of clinical manifestations complicate both diagnosis of the disease and trial of pathogenetic therapy in patients with DADA2. The article describes DADA2 patient care, as well as provides present state analysis of the DADA2 problem in the world, including terminology, historical references, pathogenesis, diagnosis problems and clinical manifestations.
