STAT3 is a crucial transcription factor involved in the regulation of immune cell activation and differentiation, with germline activating mutations linked to inborn errors of immunity. Research has made significant progress in understanding the clinical spectrum and underlying molecular mechanisms of STAT3 GOF disease, providing potential therapeutic strategies for affected patients.
Signal transducer and activator of transcription 3 (STAT3) is a key transcription factor involved in regulation of immune cell activation and differentiation. Recent discoveries highlight the role of germline activating STAT3 mutations in inborn errors of immunity characterized by early-onset multi-organ autoimmunity and lymphoproliferation. Much progress has been made in defining the clinical spectrum of STAT3 GOF disease and unraveling the molecular and cellular mechanisms underlying this disease. In this review, we summarize our current understanding of the disease and discuss the clinical phenotype, diagnostic approach, cellular and molecular effects of STAT3 GOF mutations and therapeutic concepts for these patients.
