Variant-drug associations (data source: PharmGKB)
Gene Name Variant Alleles Chemical Phenotype Category Significance Notes Sentence Publications Annotation ID
ALDH2 rs671 AA + AG nitroglycerin efficacy yes Patients without ALDH2*2 variant had greater reduction in pulmonary vascular resistance (PVR) than patients with the variant (delta1.1±0.6 Wood units·m2 vs. delta0.6±0.2 Wood units·m2, p<0.05). The haemodynamic effects of the drug were lower in patients with the ALDH2 gene polymorphisms. Genotypes AA + AG is associated with decreased response to nitroglycerin in children with Heart Defects, Congenital as compared to genotype GG. 31250045 1451094520
ALDH2 rs671 AA + AG nitroglycerin metabolism/PK yes "GTN treatment started at a dose of 2 μg/kg/min, and the dose was escalated by 1-2 μg/kg/min until pulmonary vascular resistance (PVR) was reduced by more than 30%," suggesting those with the *2 variant required higher doses and had higher plasma drug concentration. Genotypes AA + AG are associated with increased concentrations of nitroglycerin in children with Heart Defects, Congenital and Hypertension, Pulmonary as compared to genotype GG. 31250045 1451094560
ALDH2 rs671 AG ethanol other yes Healthy men with the ALDH2*1/*2 genotype had significantly higher blood ethanol levels (p,0.05), higher blood–acetaldehyde concentrations (p<0.001), significantly higher increase in pulse rate (p<0.001) and an earlier facial skin blood flow (FSBF) (p<0.001) compared to *1/*1 after one time ingesting 0.3¿g/kg of alcohol. Genotype AG is associated with increased exposure to ethanol in men as compared to genotype GG. 25365528 1450971980
ALDH2 rs671 AG ethanol metabolism/PK yes Blood alcohol concentration (BAC) was significantly higher in AG individuals compared to GG from 15 minutes to 300 minutes after alcohol dosing. Note that individuals with the AA genotype were excluded from the study. Genotype AG is associated with increased concentrations of ethanol in healthy individuals as compared to genotype GG. 31002879 1450936677
ALDH2 rs671 AG acetaldehyde metabolism/PK yes Blood concentrations of acetaldehyde, a metabolite of ethanol, were significantly higher in AG individuals compared to GG from 15 minutes to 300 minutes after alcohol dosing. Note that individuals with the AA genotype were excluded from the study. Genotype AG is associated with increased concentrations of acetaldehyde in healthy individuals as compared to genotype GG. 31002879 1450936718
