TL;DR: Mutations in SAMHD1 are described as the cause of Aicardi-Goutières syndrome at the AGS5 locus and data is presented to show that SAM HD1 may act as a negative regulator of the cell-intrinsic antiviral response.

TL;DR: A robust relationship between mutations in all seven genes with increased type I interferon activity in cerebrospinal fluid and serum, and the increased expression of interferOn‐stimulated gene transcripts in peripheral blood is observed.

TL;DR: The analysis defines the phenotypic spectrum of AGS and suggests a coherent mutation-screening strategy in this heterogeneous disorder, and indicates that at least one further AGS-causing gene remains to be identified.

TL;DR: CPA may be regarded as a separate clinical entity different to “classical” cerebral AVMs, because normal brain is interspersed with the abnormal vascular channels increasing the risk of neurological deficit in aggressive treatments, which in the light of the natural history does not seem to be indicated.

TL;DR: It is shown that biallelic mutations in the gene SNORD118, encoding the box C/D snoRNA U8, cause the cerebral microangiopathy leukoencephalopathy with calcifications and cysts (LCC), presenting at any age from early childhood to late adulthood.
