Next-Generation Sequencing Technologies and Neurogenetic Diseases

Area of Science:

• Genetics
• Neurology
• Genomic Medicine

Background:

• Neurological diseases, both Mendelian and complex, often have poorly understood genetic underpinnings.
• Next-generation sequencing (NGS) has revolutionized the study of genetic diseases.
• Effective genetic testing selection is crucial for improved diagnosis, treatment, and prevention.

Purpose of the Study:

• To provide a comprehensive overview of NGS applications in neurological disease research.
• To discuss the advantages and limitations of various NGS methods.
• To highlight NGS-based insights into specific neurogenetic diseases.

Main Methods:

• Review of NGS technologies including whole-exome sequencing (WES), whole-genome sequencing (WGS), and gene panels.
• Analysis of NGS applications in understanding genetic factors of neurological disorders.
• Case examples of NGS in Charcot-Marie-Tooth disease, spinocerebellar ataxias, epilepsy, and multiple sclerosis.

Main Results:

• NGS methods like WES and WGS are effective for identifying novel mutations.
• Gene panels are valuable for investigating specific gene roles in neurogenetic conditions.
• NGS provides critical insights into the genetic etiology of diverse neurological diseases.

Conclusions:

• NGS is an indispensable tool for unraveling the genetic basis of neurological disorders.
• Careful selection of NGS approaches optimizes diagnostic yield and research potential.
• Addressing challenges in variant interpretation is key for advancing NGS in clinical practice.
