Aicardi-Goutières syndrome: A monogenic type I interferonopathy.
Liu A, Ying S. Liu A, et al. Scand J Immunol. 2023 Oct;98(4):e13314. doi: 10.1111/sji.13314. Epub 2023 Jul 29. Scand J Immunol. 2023. PMID: 37515439 Free article. Review.
AGS may be caused by mutations in any one of nine genes (TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR1, IFIH1, LSM11 and RNU7-1) that result in accumulation of self-nucleic acids in the cytoplasm or aberrant sensing of self-nucleic acids. ...

We conclude that genomic ribonucleotides are a hitherto unappreciated source of PARP-trapping DNA lesions, and that the frequent deletion of RNASEH2B in metastatic prostate cancer and chronic lymphocytic leukaemia could provide an opportunity to exploit these findings ther …

We identified variants in 57 different genes among 91 diagnosed cases, with the most frequent being RNASEH2B, EIF2B5, POLR3A, and PLP1, and a dual diagnosis underlying complex phenotypes in 6 families, underscoring the importance of genomic analysis to solve these cases. . …

Neurologic Phenotypes Associated with Mutations in TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR1, and IFIH1: Aicardi-Goutieres Syndrome and Beyond.

It is now recognized that mutations in any of the following seven genes may result in the classical AGS phenotype: TREX1 (AGS1), RNASEH2A (AGS2), RNASEH2B (AGS3), RNASEH2C (AGS4), SAMHD1 (AGS5), ADAR1 (AGS6), and IFIH1 (AGS7). ...

PELI2 is a negative regulator of STING signaling that is dynamically repressed during viral infection.
Ritchie C, Li L. Ritchie C, et al. Mol Cell. 2024 Jul 11;84(13):2423-2435.e5. doi: 10.1016/j.molcel.2024.06.001. Epub 2024 Jun 24. Mol Cell. 2024. PMID: 38917796 Free PMC article.
PELI2 sets a threshold for STING activation that tolerates low levels of cytosolic dsDNA, such as that caused by silenced TREX1, RNASEH2B, BRCA1, or SETX. When this threshold is reached, such as during viral infection, STING-induced interferon production temporarily downre …
