Fragile X Syndrome: A Review for General Pediatricians

Area of Science:

• Genetics
• Developmental Pediatrics
• Neurodevelopmental Disorders

Background:

• Fragile X syndrome is the most frequent inherited cause of intellectual disability.
• Early identification is challenging due to delayed onset of characteristic physical features.
• Genetic testing is recommended for males and females with unexplained developmental delays, intellectual disability, or autism, especially with a family history.

Purpose of the Study:

• To highlight the importance of early identification and intervention for Fragile X syndrome.
• To emphasize the role of genetic testing in diagnosing the condition.
• To underscore the necessity of genetic counseling for affected families.

Main Methods:

• This abstract focuses on clinical presentation and management recommendations.
• It emphasizes the diagnostic utility of genetic testing in specific pediatric populations.
• It reviews the importance of early intervention services and psychological support.

Main Results:

• Classical physical features often manifest in late childhood or adolescence, complicating early diagnosis.
• Genetic testing is a key diagnostic tool for individuals presenting with developmental delays, intellectual disability, or autism.
• No specific cure exists, but early intervention and supportive care are vital.

Conclusions:

• Prompt genetic testing is crucial for early diagnosis of Fragile X syndrome in at-risk children.
• Early intervention services and psychological support can significantly improve outcomes.
• Genetic counseling is essential for families to understand inheritance patterns and reproductive risks.
