Three patients with severe bilateral frontoparietal polymicrogyria

Area of Science:

• Neuroscience
• Genetics
• Developmental Biology

Background:

• Bilateral frontoparietal polymicrogyria syndrome is a neurological disorder.
• It is characterized by diffuse polymicrogyria in the frontoparietal lobes.
• Clinical features include generalized tonic-clonic seizures and mental retardation in early childhood.

Observation:

• Patients with this syndrome can develop speech and walking abilities.
• Epilepsy is often manageable with antiepileptic drugs.
• Three cases presented with severe clinical and neuroimaging characteristics.

Findings:

• These severe cases represent a distinct, more profound form of bilateral frontoparietal polymicrogyria.
• The severity may be linked to ethnic variations or genetic factors beyond the GPR56 gene.
• Consistent clinical and neuroimaging findings were noted in these severe cases.

Implications:

• This research refines the classification of bilateral frontoparietal polymicrogyria syndrome.
• It highlights the need for further investigation into genetic and ethnic influences on disease severity.
• Understanding these factors is crucial for improved diagnosis and potential therapeutic strategies.
