DADA2 is a monogenetic autosomal recessive autoinflammatory disease characterized by high fever, livedo racemose, early-onset stroke, mild immunodeficiency, and PAN-like symptoms. Phenotypic variability is observed in patients with the same mutation.
The deficiency of adenosine deaminase 2 (DADA2) has recently been defined as a monogenetic autosomal recessive autoinflammatory disease. DADA2 is mainly characterized by high fever, livedo racemose, early-onset stroke, mild immunodeficiency and clinically polyarteritis nodosa (PAN)-like symptoms. Mutations in CECR1 (cat eye syndrome chromosome region, candidate 1) are responsible for DADA2. Livedoid racemose, lacunar infarct due to involvement in small vessel of the central nervous system, peripheral neuropathy, digital ulcers and loss of fingers are predominantly seen in the disease which could progress to end-stage organ failure and death in some patients. A wide spectrum of severity in phenotype as well as in the age of onset has been reported in the literature. This phenotypic variability is also found in our clinical practice even in patients with the same mutation. Here, we present a family diagnosed with DADA2, with the previously reported p.Gly47Arg mutation in CECR1.
