Aicardi-Goutières syndrome is an inflammatory disease occurring due to mutations
in any of TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR or IFIH1. We report
on 374 patients from 299 families with mutations in these seven genes. Most
patients conformed to one of two fairly stereotyped clinical profiles; either
exhibiting an in utero disease-onset (74 patients; 22.8% of all patients where
data were available), or a post-natal presentation, usually within the first year
of life (223 patients; 68.6%), characterized by a sub-acute encephalopathy and a
loss of previously acquired skills. Other clinically distinct phenotypes were
also observed; particularly, bilateral striatal necrosis (13 patients; 3.6%) and
non-syndromic spastic paraparesis (12 patients; 3.4%). We recorded 69 deaths
(19.3% of patients with follow-up data). Of 285 patients for whom data were
available, 210 (73.7%) were profoundly disabled, with no useful motor, speech and
intellectual function. Chilblains, glaucoma, hypothyroidism, cardiomyopathy,
intracerebral vasculitis, peripheral neuropathy, bowel inflammation and systemic
lupus erythematosus were seen frequently enough to be confirmed as real
associations with the Aicardi-Goutieres syndrome phenotype. We observed 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. We
recorded a positive correlation between the level of cerebrospinal fluid
interferon activity assayed within one year of disease presentation and the
degree of subsequent disability. Interferon-stimulated gene transcripts remained
high in most patients, indicating an ongoing disease process. On the basis of
substantial morbidity and mortality, our data highlight the urgent need to define
coherent treatment strategies for the phenotypes associated with mutations in the
Aicardi-Goutières syndrome-related genes. Our findings also make it clear that a
window of therapeutic opportunity exists relevant to the majority of affected
patients and indicate that the assessment of type I interferon activity might
serve as a useful biomarker in future clinical trials.
