Lexical and gestural development in 5p deletion syndrome-A case report
1Nord University, 8049, Bodø, Norway; Frambu Resource Centre for Rare Disorders, 14014, SIggerud, Norway.
Children with 5p deletion syndrome show delayed, not deviant, development in early gestural and vocabulary skills. Early assessment of these communicative abilities is crucial for intervention.
Area of Science:
- Developmental Psychology
- Linguistics
- Genetics
Background:
- 5p deletion syndrome (Cri du Chat syndrome) is associated with speech and language impairments.
- Early communication development, including gestures and vocabulary, is critical for overall development.
Observation:
- A longitudinal study tracked the early gestural and lexical development of one boy with 5p deletion syndrome.
- Developmental trajectories were assessed using the MacArthur-Bates Communicative Development Inventories (CDI) over five years.
Findings:
- The participant exhibited a significantly delayed, but not deviant, developmental path in receptive vocabulary, expressive vocabulary, and communicative gestures.
- Comparison was made against typically developing infants aged 8–20 months.
Implications:
- Speech and language difficulties in 5p deletion syndrome extend to gestural and lexical domains.
- Early and comprehensive assessment of gestural and lexical skills is vital for effective intervention planning.
- Findings support early intervention strategies to enhance communication in affected children.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
