 A rare neurodevelopmental disorder characterized by the classic triad of agenesis of the corpus callosum (total or partial), central chorioretinal lacunae and infantile spasms that affects almost exclusively females & rarely in 47 XXY males. However Aicardi syndrome is now recognized as a more complex, pleiotropic disorder with an expanded spectrum of phenotypical features. A rare neurodevelopmental disorder characterized by the classic triad of agenesis of the corpus callosum (total or partial), central chorioretinal lacunae and infantile spasms that affects almost exclusively females & rarely in 47 XXY males.
