Normal function
ZNFX1 gene encodes a RNA-binding protein that initiates the antiviral response and is required to restrict the replication of RNA viruses (PubMed:33872655). Acts as a double-stranded RNA (dsRNA) sensor that recognizes viral RNA and then interacts with MAVS to initiate the type I interferon response (by similarity). It is also required for immunity against some bacteria, such as mycobacteria.
Dysfunction and disease
Homozygous or compound heterozygous mutations in the ZNFX1 gene cause an immunologic disorder characterized by both immunodeficiency and recurrent infections, often to viruses or mycobacteria, as well as by hyperinflammation with systemic involvement. The disorder is thought to result from dysregulation of the interferon response to viral stimulation in the innate immune system. [Load More]
