A Case Study of Suspected Childhood Apraxia of Sign.

Purpose: We provide a case report of "Zoe," a 4-year-old deaf child from a deaf signing family, who presented with a possible case of Childhood Apraxia of Sign (CASign).

Method: The description is based on reports from the child's speech-language pathologist, her Individualized Education Program report, and a clinician-created sign imitation task.

Results: Zoe's sign articulation errors in American Sign Language differed from those reported for typically developing deaf children and were parallel to the types of errors observed for hearing children with childhood apraxia of speech.
