Speech characteristics in the Kabuki syndrome

Area of Science:

• Genetics
• Speech-Language Pathology
• Pediatric Medicine

Background:

• Kabuki syndrome is a rare genetic disorder with diverse clinical manifestations.
• Speech and language impairments are common in individuals with Kabuki syndrome.
• Understanding specific speech patterns is crucial for targeted interventions.

Purpose of the Study:

• To investigate the detailed speech characteristics in children with Kabuki syndrome.
• To analyze the maturation of speech parameters (articulation, pitch, loudness, prosody) over time.
• To identify challenges for speech-language pathology services in managing these individuals.

Main Methods:

• A cohort of six children with Kabuki syndrome was studied.
• Speech was assessed for articulation, intelligibility, pitch, loudness, and prosody.
• Longitudinal evaluation of two participants from childhood to adolescence was performed.

Main Results:

• All participants exhibited articulation errors and abnormal oral resonance, attributed to hypotonia and poor oral-motor coordination.
• Speech and language acquisition were delayed in all six children.
• Pitch, loudness, and prosody failed to mature appropriately into adolescence in the two longitudinally studied individuals, despite articulation improvements.

Conclusions:

• Kabuki syndrome is associated with distinctive speech characteristics, including a lack of maturation in pitch and loudness.
• These persistent speech differences present challenges for social integration and require tailored therapeutic approaches.
• Identifying these specific speech patterns aids in expanding the clinical understanding of Kabuki syndrome and refining treatment strategies.
