Herpes simplex virus 1 (HSV-1) infects several billion people worldwide and can cause life threatening herpes simplex encephalitis (HSE) in some patients. Monogenic defects in components of the type I interferon system have been identified in HSE patients, emphasizing the role of inborn errors of immunity underlying HSE pathogenesis. Here, we identify compound heterozygous loss-of-function mutations in the gene GTF3A encoding for transcription factor IIIA (TFIIIA), a component of the RNA polymerase III complex, in a patient with common variable immunodeficiency (CVID) and HSE. Patient fibroblasts and GTF3A gene-edited cells displayed impaired HSV-1-induced innate immune responses and enhanced HSV-1 replication. ChIP-seq analysis identified the 5S ribosomal RNA pseudogene 141 (RNA5SP141), an endogenous ligand of the RNA sensor RIG-I, as a transcriptional target of TFIIIA. GTF3A mutant cells exhibited diminished RNA5SP141 expression and abrogated RIG-I activation upon HSV-1 infection. Our work unveils a crucial role for TFIIIA in transcriptional regulation of a cellular RIG-I agonist and shows that GTF3A genetic defects lead to impaired cell-intrinsic anti-HSV-1 responses and can predispose to HSE. GTF3A mutations impair HSV-1 control by abrogating transcription of the endogenous RIG-I ligand RNA5SP141.
