Insights
The Adenosine triphosphate-binding cassette transporter A1 (ABCA1) R219K gene polymorphism is not associated with lacunar infarction (LI) complicated by arteriosclerosis. This study found no genetic link between ABCA1 R219K and LI with arteriosclerosis.
Area of Science:
- Genetics
- Cardiovascular Disease
- Biochemistry
Background:
- Lacunar infarction (LI) combined with arteriosclerosis is a significant health concern.
- The role of Adenosine triphosphate-binding cassette transporter A1 (ABCA1) gene polymorphism in LI with arteriosclerosis requires further investigation.
- Understanding genetic predispositions can aid in developing targeted prevention strategies.
Purpose of the Study:
- To investigate the association between Adenosine triphosphate-binding cassette transporter A1 (ABCA1) gene R219K polymorphism and lacunar infarction (LI) complicated with arteriosclerosis.
- To analyze serum lipid profiles and apolipoprotein levels in patients with LI and arteriosclerosis compared to healthy controls.
- To determine the correlation between ABCA1 R219K genotypes and susceptibility to LI with arteriosclerosis.
Main Methods:
- Case-control study involving 112 LI patients with arteriosclerosis and 342 healthy controls.
- Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) used to detect ABCA1 R219K gene polymorphism.
- Serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), apolipoprotein A-I (ApoA-I), apolipoprotein B (ApoB), and lipoprotein (a) [Lp(a)] were measured.
Main Results:
- Patients with LI and arteriosclerosis exhibited significantly higher TG and ApoB levels, and lower ApoA-I and HDL-C levels compared to controls.
- No significant differences were observed in the frequencies of RR, RK, and KK genotypes or allele frequencies of ABCA1 R219K between the two groups.
- Serum lipid and apolipoprotein levels did not show significant differences among different ABCA1 R219K genotypes.
Conclusions:
- The Adenosine triphosphate-binding cassette transporter A1 (ABCA1) R219K polymorphism is not correlated with the susceptibility to lacunar infarction complicated with arteriosclerosis.
- While lipid profiles differ between patients and controls, the ABCA1 R219K genotype does not appear to be a contributing genetic factor.
- Further research may explore other genetic variants or environmental factors influencing LI combined with arteriosclerosis.
Abstract:
Adenosine triphosphate-binding cassette transporter A1 (ABCA1) gene polymorphism in lacunar infarction (LI) combined with arteriosclerosis was investigated. A total of 112 LI patients complicated with arteriosclerosis treated in Ningbo First Hospital from March 2015 to September 2016 were enrolled as observation group. At the same time, 342 healthy subjects were selected from physical examination center to serve as the control group. The ABCA1 gene polymorphism was detected via polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and the susceptibility of ABCA1 gene to LI complicated with atherosclerosis was studied. There were no significant differences in serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and lipoprotein (a) [Lp(a)] between the two groups (P>0.05). Levels of triglyceride (TG) and apolipoprotein B (ApoB) in observation group were significantly higher than those in control group, but levels of ApoA-I and high-density lipoprotein cholesterol (HDL-C) were significantly lower in observation group than those in control group (P<0.05). There were no significant differences in the RR, RK and KK frequencies and allele frequency of ABCA1 R219K genotype between the two groups (P>0.05). Moreover, levels of HDL-C increased in the RR, RK and KK genotypes, but were not statistically significant (P>0.05). Levels of TG, TC, LDL-C, ApoA-I, ApoB and Lp(a) showed no significant differences among different genotypes of ABCA1 R219K (P>0.05). Results indicated that ABCA1 R219K polymorphism has no correlation with LI complicated with arteriosclerosis.
