Noonan syndrome is an autosomal dominant, genetic, multisystem disorder with a prevalence of 1 in 1000–2500 live births. Characteristic features of the condition include distinctive myopathic facial features, hypertelorism, short and broad nose, webbed neck, and low set ears. About 10% of the subjects have auditory defects due to sensorineural hearing loss. The patient also has short stature, chest deformity (superior pectus carinatum and inferior pectus excavatum), widely spaced nipples, and delayed puberty. A rare psychiatric manifestation of somnambulism and somniloquy in a case of Noonan syndrome is reported.
