Novel adenosine deaminase 2 mutations in a child with a fatal vasculopathy.

UNLABELLED: Adenosine deaminase 2 (ADA2) deficiency due to CECR1 mutations is a recently defined disorder that involves systemic inflammation and vasculopathy often associated with polyarteritis nodosa. We report on a 5-year-old girl with a severe vasculopathy who carried two novel mutations in CECR1.

CONCLUSION: Identification of CECR1 mutations in patients with vasculopathy may lead to earlier diagnosis of ADA2 deficiency.
