pUNO1 bearing the human STING gene, N154S variant
SAVI-associated N154S hSTING gene
STING (stimulator of interferon genes; also known as TMEM173, MITA, MPYS, and ERIS) is essential for the interferon (IFN) response to microbial or self DNA, and acts as a direct sensor of cyclic dinucleotides (CDNs) .
Several variants of STING have been described in the human population. The allele S154 contains a unique point mutation (N154S) in the “wild-type” R232-RGR hSTING variant.
This mutation confers gain-of-function and constitutive activation of STING with an upregulation of IFN production. It is associated with a chronic autoinflammatory disease, known as STING-associated vasculopathy with onset in infancy (SAVI) .
