Advances in chromosomal microarray analysis: Transforming neurology and neurosurgery

Area of Science:

• Genomics
• Clinical Diagnostics
• Neurology

Background:

• Genomics has transformed clinical understanding over the past two decades.
• Chromosomal Microarray Analysis (CMA) is a sensitive technique for detecting submicroscopic chromosomal imbalances.
• CMA examines DNA for copy number variations, deletions, duplications, and structural differences.

Purpose of the Study:

• To review the pivotal role of CMA in bridging genomics and clinical practice in neurology.
• To highlight CMA's potential in advancing personalized medicine and reshaping neurogenetics.
• To discuss the clinical utility of CMA across diverse neurological conditions.

Main Methods:

• Review of current literature on CMA applications in neurology.
• Analysis of CMA's impact on diagnosis, treatment, and patient outcomes.
• Identification of challenges and future directions for CMA implementation.

Main Results:

• CMA revolutionizes neurological diagnoses, enabling personalized treatment plans and improved patient outcomes.
• It provides crucial insights into neurodevelopmental disorders, CNS tumors, neurodegenerative diseases, cerebrovascular diseases, and epilepsy.
• CMA aids in diagnosing autism, intellectual disabilities, and identifying genetic causes of drug-resistant epilepsy, while also stratifying risk for cerebrovascular diseases.

Conclusions:

• CMA is a key genomic tool with significant clinical utility in neurology.
• Addressing challenges like variant interpretation and accessibility will optimize CMA's impact.
• CMA holds immense potential to transform neurogenetics and enhance patient care through precision medicine.
