Germline mutations of signal transducer and activator of transcription 3 (STAT3) are responsible for 2 distinct human diseases: autosomal-dominant hyper-IgE syndrome (AD-HIES) caused by STAT3 loss-of-function mutations and STAT3 gain-of-function disease. So far, these entities have been regarded as antithetic, with AD-HIES mainly associated with characteristic infections and a connective tissue phenotype and STAT3 gain-of-function characterized by lymphoproliferation and poly-autoimmunity. The R335W substitution in the DNA-binding domain of STAT3 was initially described in 2 patients with typical AD-HIES, but paradoxically, recent functional analysis demonstrated a gain-of-function effect of this variant.

Abstract
Germline mutations of signal transducer and activator of transcription 3 (STAT3) are responsible for 2 distinct human diseases: autosomal-dominant hyper-IgE syndrome (AD-HIES) caused by STAT3 loss-of-function mutations and STAT3 gain-of-function disease. So far, these entities have been regarded as antithetic, with AD-HIES mainly associated with characteristic infections and a connective tissue phenotype and STAT3 gain-of-function characterized by lymphoproliferation and poly-autoimmunity. The R335W substitution in the DNA-binding domain of STAT3 was initially described in 2 patients with typical AD-HIES, but paradoxically, recent functional analysis demonstrated a gain-of-function effect of this variant.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
