Apolipoprotein A1 rs5070 A/G polymorphism with stroke subtypes in Taiwan

Area of Science:

• Genetics
• Cardiovascular Disease
• Metabolic Disorders

Background:

• Apolipoprotein A1 (ApoA1) is crucial for high-density lipoprotein cholesterol and lipid metabolism.
• Apolipoprotein A1 (ApoA1) plays a role in cholesterol regulation.
• This study investigates the link between ApoA1 gene variations and stroke subtypes.

Purpose of the Study:

• To examine the association between Apolipoprotein A1 (ApoA1) polymorphism (rs5070) and stroke subtypes in Taiwanese individuals.
• To identify potential genetic risk factors for different types of stroke.

Main Methods:

• Genotyping of ApoA1 rs5070 polymorphism using polymerase chain reaction and mass spectrometry.
• Analysis of 2139 participants, including controls and cases of large artery atherosclerosis (LAA), small-vessel occlusion, and hypertensive intracranial hemorrhage.
• Statistical analysis to compare genotype frequencies and assess odds ratios.

Main Results:

• No significant difference in ApoA1 rs5070 genotype frequencies was observed between stroke subtypes and controls.
• Diabetic patients with the AG+GG alleles of ApoA1 rs5070 had a 1.58-fold increased likelihood of developing LAA stroke compared to those with the AA allele.
• The risk was higher in male diabetic patients, with an odds ratio of 1.90.

Conclusions:

• Apolipoprotein A1 (ApoA1) rs5070 A/G polymorphism may contribute to the susceptibility of large artery atherosclerosis (LAA) stroke.
• The association appears particularly significant in male diabetic patients.
• This genetic polymorphism could be a risk factor for specific stroke subtypes in certain populations.
