Developing with ring 14 syndrome: a survey in different countries.

Area of Science:

• Genetics
• Developmental Pediatrics
• Linguistics

Background:

• Ring 14 syndrome and 14q deletions are rare chromosomal abnormalities impacting development.
• Communicative skills in affected individuals exhibit significant variability.
• Understanding these skills is crucial for supportive care and intervention.

Purpose of the Study:

• To evaluate communicative and language development in individuals with ring 14 syndrome and 14q deletions.
• To explore correlations between language skills and genetic, clinical, psychomotor, and behavioral factors.
• To identify factors influencing developmental trajectories in this population.

Main Methods:

• A questionnaire, developed in five languages, was administered to parents of 36 participants.
• Data collected included genetic, clinical, psychomotor, and behavioral characteristics.
• Statistical analysis was performed to identify relationships and compare subgroups.

Main Results:

• Chronological age did not explain the wide range of skill variability observed.
• Individuals with ring 14 syndrome had higher rates of epilepsy, retinal abnormalities, and autism.
• A higher level of language development was associated with smaller amounts of deleted genetic material.

Conclusions:

• Genetic factors, particularly the extent of deletion, significantly influence language development.
• Ring 14 syndrome presents with distinct clinical features compared to linear 14q deletions.
• This study provides valuable data for predicting developmental outcomes in rare chromosomal disorders.
