To the Editor:Gain-of-function mutations in TMEM173,which encodes the protein stimulator of interferon(IFN)genes(STING),can reportedly cause an autoinflammatory syndrome termed STING-associated vasculopathy with onset in infancy(SAVI).1-3 SAVI is characterized by cutaneous necrotic lesions,growth failure,systemic inflammation,and interstitial lung disease.1,4 Therapeutic management is challenging and difficult:steroids are only partially effective,and patients respond poorly to immunosuppressants.
