Childhood Motor Speech Disorders in a Child with 7q11.23 Duplication Syndrome
DC was a female child enrolled in a longitudinal study of children with 7q11.23 duplication syndrome, a genetic disorder characterized by CAS, symptoms of CD (e.g., low muscle tone), and social anxiety at the age of 2.2 years. DC lived with her mother, one younger brother, and two older half-brothers. Her mother was a supportive advocate for DC and sought opportunities to ensure that her communication, developmental, and educational needs were met. Her speech, language, and cognitive abilities were evaluated five times between the ages of 2.2 and 8.9 years.
