Syndrome with the presence of microcephaly and intracranial calcifications at birth accompanied by neurological delay, seizures and a clinical course similar to that seen in patients after intrauterine infection with Toxoplasma gondii, Rubella, Cytomegalovirus, Herpes simplex (so-called TORCH syndrome), or other agents, despite repeated tests revealing the absence of any known infectious agent. The clinical presentation of the reported cases is rather heterogeneous with variable manifestations including intrauterine growth retardation, hepatosplenomegaly, cerebellar hypoplasia or atrophy and congenital cataract. The cause remains unknown. Several familial cases, compatible with an autosomal recessive pattern of inheritance have been described.
