Chromosomal translocation in a child with SLI and apraxia
1Montclair State University, NJ, USA.
Insights
A chromosomal translocation was identified in a child with severe expressive language impairment and verbal apraxia. This case study explores the potential link between chromosomal abnormalities and speech and language disorders.
Area of Science:
- Genetics
- Developmental Pediatrics
- Speech-Language Pathology
Background:
- A 5-year-old boy diagnosed with preschool handicaps presented with specific expressive language impairment and verbal apraxia.
- Standard developmental assessments were conducted, including neurological, speech/language, cognitive, and play evaluations.
Observation:
- Chromosomal studies revealed a de novo balanced translocation involving the first and second chromosomes.
- The child exhibited a severe deficit in expressive speech and language skills.
- Notably, the child demonstrated strong nonverbal cognitive and communicative abilities.
Findings:
- The case presents a potential correlation between a chromosomal translocation and the development of speech and language disorders.
- The specific translocation may impact the neural pathways responsible for expressive language production.
Implications:
- This case highlights the importance of considering genetic factors in the etiology of childhood speech and language impairments.
- Further research into chromosomal abnormalities and their effects on speech development is warranted.
- Early identification and targeted interventions may benefit children with similar genetic profiles and language deficits.
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.
