-
A neurological disorder with characteristics of moderate to severe developmental delay and intellectual disability and mild dysmorphic features. Early symptoms include hypotonia, delayed development of motor skills, speech delay, hypertelorism, broad nasal bridge, and fingers with tapered ends. Other features include microcephaly, seizures, recurrent ear infections, strabismus, amblyopia and hyperopia. Behavioral problems such as hyperactivity, attention deficit disorder, aggression, anxiety and autism spectrum occur in some cases. Caused by mutations in the HIVEP2 gene leading to a shortage of functional HIVEP2 protein. Inherited in an autosomal dominant pattern however most cases of this condition result from de novo mutations in the gene.
