Question

How can Noonan syndrome affect a person's speech?

Answer

My experience with patients with Noonan's syndrome has been for feeding problems. However, according to Shprintzen's Syndrome Identification for Speech-Language Pathology (2000), an individual with Noonan's may have many obligatory articulation errors related to malocclusion. Persons with Noonan's may have class II malocclusion, anterior skeletal open-bite, and a constricted maxillary arch. There is a low frequency of cleft, but if present may be submucous and result in compensatory articulation patterns secondary to velopharyngeal insufficiency. Individuals with Noonan's may have cognitive impairment which may affect expressive language more than receptive language.
