Name: | infantile spasms-broad thumbs syndrome |
Definition: | Infantile spasms-broad thumbs syndrome is a rare neurologic disorder characterized by profound developmental delay, facial dysmorphism (i.e. microcephaly, large anterior fontanel, hypertelorism, downslanting palpebral fissures, beaked nose, micrognathia), broad thumbs and flexion and/or extension spasms. Bilateral cataracts, hypertrophic cardiomyopathy and hydrocele have also been reported. EEG shows hypsarrhythmic features and MRI may reveal partial agenesis of the corpus callosum, mild brain atrophy and/or ventriculomegaly. There have been no further descriptions in the literature since 1990. |
