Atypical phenotype of an old disease or typical phenotype of a new disease: deficiency of adenosine deaminase 2

Abstract

Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive autoinflammatory disorder caused by mutations in CECR1 (cat eye syndrome chromosome region, canditate 1) gene, which encodes the enzyme adenosine deaminase 2 necessary for endothelial cell survival and function.
