regulator of multiple, diverse cellular processes. Heterozgyous, germline, loss-of-function
mutations in STAT3 lead to the primary immune deficiency Hyper-IgE syndrome.
Heterozygous, somatic, gain-of-function mutations in STAT3 have been reported in
malignancy. Recently, germline, heterozygous mutations in STAT3 that confer a gain-of-
function have been discovered and result in early-onset, multi-organ autoimmunity. This …
