Intellectual disability with language impairment and with or without autistic features is a neurodevelopmental disorder characterized by global developmental delay with moderate to severe speech delay that particularly affects expressive speech. Most patients have articulation defects, but frank verbal dyspraxia is not observed. Common dysmorphic features include broad forehead, downslanting palpebral fissures, short nose with broad tip, relative macrocephaly, frontal hair upsweep, and prominent digit pads. Gross motor skills are also delayed. Some patients have autistic features and/or behavioral problems. All reported cases have occurred de novo (review by Le Fevre et al., 2013). The disease is intellectual disability with language impairment (EFO_1001500, an Experimental Factor Ontology term). Also known as: intellectual disability with language impairment and autistic features, intellectual disability with language impairment and with or without autistic features, intellectual disability with language impairment without autistic features.
