Type I interferonopathies refers to a recently described set of monogenic diseases in which an upregulation of type I interferons is central to their pathogenesis and covers a spectrum of conditions including Aicardi-Goutières Syndrome (AGS), which is a rare genetic disorder most consistently affecting the brain and the skin. The seven AGS-associated genes encode proteins that are involved in either nucleic acid metabolism, one of which, are variants in the gene ADAR that cause Loss-of-Function (recessive or dominant-negative). Studies of the AGS-related protein like ADAR1, suggest that an inappropriate accumulation of self-derived nucleic acids can induce type I interferon signaling (PMID: 24183309; 27643693;25604658;25769924). The interferon signature appears to be a very good marker of disease and the diagnostic criteria for AGS includes the persistent elevation of mRNA levels of interferon-stimulated gene transcript observed in the peripheral blood of almost all cases of AGS with mutations in TREX1, RNASEH2A, RNASEH2C, SAMHD1, ADAR1 and IFIH1, and in 75% of patients with mutations in RNASEH2B (PMID:24183309)

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
