ZNFX1

Chr 20AR

zinc finger NFX1-type containing 1

Also known as: IMD91

The protein functions as a double-stranded RNA sensor that recognizes viral RNA and initiates the type I interferon response by interacting with MAVS, and is also required for immunity against bacteria including mycobacteria. Autosomal recessive mutations cause immunodeficiency 91 and hyperinflammation, characterized by increased susceptibility to viral and bacterial infections. The gene is highly constrained against loss-of-function variants (pLI = 1.00, LOEUF = 0.25), indicating that heterozygous loss-of-function variants are likely not tolerated in the general population.

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
