In last decades, many scholars have studied the relationship between aldehyde dehydrogenase 2 (ALDH2) rs671 and ischemic stroke (IS), however, the results obtained from these studies were inconclusive. The purpose of this study was to investigate the association between rs671 and the risk of IS by systematically review.Two researchers independently screened relevant published literatures, derived data and estimated the risk of bias of the research in Pubmed, Embase, Ovid, China National Knowledge Infrastructure (CNKI), Cochrane Library and China Biomedical Literature Database throughout March 29, 2020. All statistical analyses were performed with the Stata 12.0 software. The data of the study was analyzed using fixed and random effects models. The results were expressed by odds ratio (OR) and 95% confidence interval (95%CI).A total of 10 articles were included this study. The total number of samples for all studies was 5265, including 2762 cases and 2503 controls. Statistical results indicated statistical differences between ALDH2 rs671 polymorphism and IS under dominant model (AA vs. AG + GG) and allelic model (A vs G), ORs (95% CI) were 1.66 (1.27-2.17) (P = .00) and 1.34 (1.05-1.71) (P = .02), respectively. But there was no statistical difference under recessive model (AA + AG vs GG), OR (95% CI) was 1.40 (0.99-1.97), P = .06.ALDH2 rs671 polymorphism was related to IS risk for Chinese population and the A allele of rs671 may be a risk factor of IS.

Objective: The aetiology of epilepsy is known to have genetic contributions, yet results from genome-wide association studies (GWAS) have not always been consistent. We undertook a systematic review in order to identify risk variants for epilepsy.
Methods: This systematic review was conducted in accordance with the PRISMA protocol.

Insulin resistance is a major indicator of cardiovascular diseases, including hypertension. The Metabolic Score for Insulin Resistance (METS-IR) offers a simplified and cost-effective way to evaluate insulin resistance. This study aimed to identify genetic variants associated with the prevalence of hypertension stratified by METS-IR score levels.

Article Synopsis
- - The study investigates the link between genetic variants in the ALDH2 and ADH1B genes and the risk of lung adenocarcinoma (LAD), a type of lung cancer, using data from 150 LAD patients and two control groups from Taiwan.
- - Results show that the ALDH2 rs671 *2/*2 variant significantly increases the risk of developing LAD, with females showing an even stronger association compared to males.
- - No significant relationship was found between the ADH1B rs1229984 variant and LAD risk, highlighting the specific impact of the ALDH2 gene in this population.
Article Synopsis
- - The study highlights the connection between alcohol consumption and lung cancer, focusing on the inactivating mutation in the ALDH2 enzyme prevalent in Asian populations, which impacts acetaldehyde clearance.
- - Through a bioinformatic analysis of multi-omics data, researchers found that ALDH2 is significantly expressed in healthy lung tissue but less so in lung adenocarcinoma (LUAD), affecting key cellular processes and correlating with poorer patient prognosis.
- - The findings suggest that understanding ALDH2's role in lung cancer could lead to its use as a prognostic marker and a target for therapies aimed at enhancing immune responses in LUAD patients.

Article Synopsis
- The study investigates how genetic variations in the ADH1B and ALDH2 genes affect developmental outcomes in children based on maternal alcohol consumption during pregnancy in a Japanese population.
- Analyzing data from 1727 mother-child pairs, it finds that children of mothers who drank alcohol during pregnancy are at a significantly higher risk for communication delays.
- Specifically, genetic differences in the ALDH2 gene increase the risk of developmental delays, highlighting the importance of both genetic and environmental factors in child development.
