Objective: Genetic polymorphisms in ALDH2 and C12orf30 genes have been reported to increase the risk of developing esophageal squamous cell carcinoma (ESCC). This study aims to investigate the relationship between ALDH2 rs671 and c12orf30 rs4767364 polymorphisms in the chromosome 12q24 gene, and risk and prognosis of individuals developing esophageal cancer (ESCC) in Xinjiang Kazak and Han populations.
Methods: The case group consisted of 127 ESCC patients. The control group comprised of 125 healthy individuals. Subjects that were recruited all come from Xinjiang province. TaqMan and the Hardy-Weinberg equilibrium were the main methods employed to detect and examine the distribution of genotypes of rs671 and rs4767364.
Results: The genotype frequencies of ALDH2 rs671 between the Kazak case and control groups were statistically significant, while no significant difference was observed between the Han case and control groups (P>.05). Moreover, ALDH2 rs671 (G>A) was associated with poor prognosis of ESCC in both Kazak and Han populations, and c12orf30 rs4767364 (A>G) was also connected with poor prognosis of ESCC in Kazak but not in Han population.
Conclusion: In the chromosome 12q24 locus, ALDH2 rs671 (G>A) is related to the susceptibility to ESCC in Kazak populations, and it is also associated with poor prognosis of EC in Kazak and Han populations. Furthermore, c12orf30 rs4767364 (A>G) may be correlated with poor ESCC prognosis in Kazak population.

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.
The Genetic Variants Influencing Hypertension Prevalence Based on the Risk of Insulin Resistance as Assessed Using the Metabolic Score for Insulin Resistance (METS-IR).

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.
Maternal alcohol consumption during pregnancy and child development: Role of ADH1B and ALDH2 gene polymorphisms-The Yamanashi Adjunct Study of the Japan Environment and Children's Study.

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.
