Genetic assessment of cortical malformations

Area of Science:

• Neuroscience
• Medical Genetics
• Radiology

Background:

• Malformations of cortical development (MCD) represent a heterogeneous group of structural brain abnormalities.
• These conditions are frequently identified in patients presenting with seizure disorders and/or developmental delay.
• Magnetic Resonance (MR) imaging plays a pivotal role in their detection and classification.

Purpose of the Study:

• To highlight the importance of MR imaging in classifying MCD.
• To emphasize the role of genetic testing in the diagnostic work-up of MCD.
• To discuss the implications of genetic findings for prognosis, therapy, and family recurrence risks.

Main Methods:

• Review of clinical and imaging data in patients with MCD.
• Integration of clinical information, family history, and MR imaging findings.
• Application of genetic testing for identifying underlying genetic alterations.

Main Results:

• MR imaging is crucial for classifying MCD.
• Genetic testing identifies underlying genetic alterations in a significant subset of patients.
• Genetic findings provide prognostic information and guide therapeutic decisions.

Conclusions:

• Genetic testing is an integral part of the interdisciplinary diagnostic approach for MCD.
• Identifying genetic causes of MCD is essential for prognostic assessment and treatment planning.
• Genetic forms of MCD necessitate genetic counseling regarding recurrence risks and reproductive options.
