Chromosomal Translocation in a Child With SLI and Apraxia

Abstract

A case study is presented of a 5-year-old boy who was classified as preschool handicapped and was assessed as having a specific expressive language impairment with verbal apraxia. Chromosomal studies revealed a de novo (new) balanced translocation between first and second chromosomes. Results of the neurological, speech/language, cognitive, and play evaluations revealed a child with a severe expressive speech-language deficit but good nonverbal cognitive and communicative skills. The hypothesis of a relationship between a chromosomal translocation and speech/language disorders is explored.
