SOAT1 and early-onset autosomal dominant Alzheimer disease: More recently, Salih et al. [33] identified a number of interferon signaling genes to be in co-expression network that is expressed in amyloid-responsive mouse microglia, including Oas and Ifit family members, and transcription factors such as Irf7 and Stat. The authors further found that Alzheimer’s disease loci colocalize with cis-eQTLs targeting OAS1 in interferon-γ stimulated iPSC-derived macrophages.
