Angelman Syndrome: A Case Report

Area of Science:

• Neurogenetics
• Developmental Pediatrics

Background:

• Angelman syndrome (AS) is a genetic disorder affecting neurodevelopment.
• It results from deletions on chromosome 15q11-q13, impacting gene expression.
• AS is characterized by developmental delay, speech impairment, seizures, and specific facial features.

Observation:

• An eight-year-old boy presented with speech delay at a neurology clinic.
• Clinical manifestations included ataxia, unusual laughter, intellectual disability, and mandibular prognathism.
• Initial metabolic screening and brain MRI results were within normal limits.

Findings:

• Genetic analysis provided a definitive diagnosis of Angelman syndrome.
• The patient's presentation aligns with the known phenotype of AS.
• This case highlights the importance of genetic testing in diagnosing AS.

Implications:

• Early diagnosis of Angelman syndrome is crucial for timely intervention.
• Understanding the genetic basis aids in accurate diagnosis and genetic counseling.
• This case contributes to the clinical understanding of Angelman syndrome presentation.
