To the Editor,

At least 18 different single-gene disorders have been described associated with elevated levels of type I interferon. These “type I interferonopathies” typically result in severe pediatric disorders, including STING-associated vasculopathy of infancy (SAVI) caused by gain of function mutations in TMEM173, spondyloenchondropdysplasia (SPENCD) caused by biallelic ACP5 mutations, and Aicardi-Goutières syndrome (AGS) caused by mutations in one of seven different genes: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, ADAR1, SAMHD1, or IFIH1 [1]. AGS is the most commonly recognized interferonopathy and in over 90% of cases presents within the first year of life with neurological impairment associated with intracranial calcification and leukodystrophy, and in around a third of cases acral chilblains develop [2]. The type I interferonopathies occur due to aberrant metabolism of nucleic acids/dysregulation of the interferon pathway, resulting in induction of type I interferon and...

Key message

Type I interferonopathies, including RNASEH2B mutations, should be considered in adults with severe digital ischemia.
