Educating friends, family, and … ), and 2 to 12 times more likely to develop esophageal cancer compared to people with normal ALDH2*1 [17-25]. ALDH2 deficiency promotes liver cancer by activating oncogenic pathways via oxidized DNA-enriched extracellular vesicles [40]. ALDH2 deficiency resulting from a Glu504Lys substitution (rs671, hereinafter referred to as the A allele) is highly prevalent in East Asian populations. Therefore, it is particularly important for university health professionals to be aware of the relationship between ALDH2-deficiency, facial flushing, and alcohol-related cancer risk. Inactive ALDH2 is an independent risk factor for pancreatic cancer, but inactive ALDH2 might not be a risk for colon cancer. Inhibition of ALDH2 by disulfirm could further increase the level of ROS, which could be highly cytotoxic in ALDH2-deficient cancer …

Those with ALDH2 Deficiency are at a significantly increased risk of gastric and esophageal cancer. In addition, the research on ALDH2 deficiency is relatively new. The A allele (Lys504) acts as a dominant negative, since the variant form can suppress the activity of the Glu504 form (G allele) in GA heterozygotes by the formation of heterotetramers. Head and neck cancer.

Studies indicate that heavy drinkers with ALDH2 Deficiency are at a more than 70 times increased risk to develop esophageal cancer.

ALDH2 Deficiency has serious health implications and should not be taken lightly. Alcoholics with an ALDH2 polymorphism have an increased risk of digestive tract cancer development, however, the link between ALDH2 deficiency and hepatocellular carcinoma (HCC) development has not been well established. Alcohol flush reaction (AFR) is a condition in which a person develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages.The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol, and is caused by an aldehyde dehydrogenase 2 deficiency. The discrepancy may be due to the following reasons: 1. In a meta-analysis of six case-control studies (945 cases and 2917 controls), Boccia et al.

Awareness of Acetaldehyde-Related Cancer. When you drink alcohol (ethanol or ethyl alcohol), the liver converts it to acetaldehyde.

Research has shown that facial flushing when drinking is indicative of ALDH2 deficiency, which can increase the risk of developing esophageal cancer by six to ten times.

Evidence That ALDH2 Deficiency Increases the Risk of Alcohol-Related Squamous Cell Esophageal Cancer. This will not only help you drink more comfortably but also help you avoid serious health risks specific to people with this condition. reported a reduced risk of head and cancer among individuals with ALDH2*2/*2 genotype, likely due to the lower consumption of alcohol among these individuals [].In addition, ALDH2*1/*2 genotype showed gene-environment interaction with the level of alcohol consumption []. Enzymes (proteins that control the breakdown of foods) are less active or inactive due to the mutation. Drinking and smoking are important risk factors in developing these cancers. Overall, global awareness of ALDH2 deficiency and its causal relationship with cancer remains relatively low. Some time the entire body gets flushed if the deficiency of Aldh2 is pronounced. A new study has shown that gene therapy to treat one of the most common hereditary disorders, aldehyde dehydrogenase type 2 (ALDH2) deficiency, may prevent increased risk for esophageal cancer … Molecular Location: base pairs 111,766,933 to 111,817,532 on chromosome 12 (Homo sapiens Updated Annotation Release 109.20200522, GRCh38.p13) (NCBI)

From the above facts people with Aldh2 deficiency should avoid alcohol in any form.
