Cerebral thrombotic microangiopathy was found at autopsy in one of two sisters with
Aicardi-Goutieres syndrome, whereas the other revealed increased serum levels of anticardiolipin
IgG antibodies (measured only in the living sister); both typical features of systemic
lupus erythematosus. These findings add support to the suggestion that Aicardi-Goutieres
syndrome and systemic lupus erythematosus are closely related disorders in which dysregulated
production of interferon-α might play a crucial role.
Aicardi-Goutieres syndrome - thrombotic microangiopathy - antiphospholipid antibodies
- systemic lupus erythematosus - interferon
