STAT2 (P52630) variants and mutations

STAT2 (also known as P52630) is a human protein-coding gene encoding a signal transducer and activator of transcription 2 protein. It partners with STAT1 and IRF9 to execute type I interferon antiviral transcriptional programs. Biallelic loss-of-function variants can cause severe viral susceptibility, while gain-of-function variants can produce chronic interferon-driven inflammatory disease. This analysis covers 1,035 STAT2 variants and mutations. Of these, 77% have computational variant effect predictions. Disease context includes primary immunodeficiency with post-measles-mumps-rubella vaccine viral infection, pseudo-TORCH syndrome 3, and COVID-19. Example STAT2 variants include M1?, A2T, and A2V.
