Özet

Aicardi-Goutieres syndrome (AGS) is a rare, autosomal recessively inherited, immune-mediated neurodevelopmental disorder. The syndrome causes infantile-onset progressive encephalopathy characterized by the neuroradiologic features of basal ganglia and periventricular white matter calcification, leucodystrophy and cerebral atrophy. Lymphocytosis and elevated levels of interferon alpha (IFN-alpha) in the cerebrospinal fluid are supplementary findings of AGS. It is frequently misdiagnosed as sequelae of congenital infection (pseudo-TORCH) and mostly recognized later. We describe three AGS cases with different clinical presentation, two male siblings with RNASEH2C mutation and a boy with TREX1 mutation. These cases highlight the importance of considering AGS in the differential diagnosis of unexplained leukoencephalopathy and developmental delay. We suggest to search for intracranial calcification, especially if there are more than one affected cases in a family.
