Stroke genetics: discovery, biology, and clinical applications

Area of Science:

• Neurology
• Genetics
• Vascular Biology

Background:

• Stroke is a major global health concern with a significant heritable component.
• Recent advancements in gene discovery have identified numerous single-gene disorders and common variants associated with stroke risk.

Purpose of the Study:

• To review the impact of genetic discoveries on understanding stroke.
• To highlight novel mechanisms and pathways implicated in different stroke types.
• To discuss the potential of genetics in stroke prevention and treatment.

Main Methods:

• Review of recent genetic studies and discoveries related to stroke.
• Analysis of genetic loci linked to stroke risk.
• Exploration of genetic influences on stroke subtypes and risk factors.

Main Results:

• Identification of approximately 35 genetic loci associated with stroke risk.
• Elucidation of novel genetic mechanisms in large artery atherosclerosis, cardioembolism, and small vessel disease.
• Established causal genetic relationships with stroke risk factors.

Conclusions:

• Genetics provides crucial insights into stroke etiology and risk.
• Genome-wide polygenic scores can identify high-risk individuals.
• Further research is needed to integrate genetics into precision medicine for stroke care, focusing on rare variants, ancestral diversity, and multi-omics data integration.
