Aldehyde dehydrogenase 2*2 (ALDH2*2) is a genetically mutated enzyme that affects the liver's ability to break down acetaldehyde, resulting in immediate negative physical effects following alcohol consumption. This usually leads to reduced lifetime alcohol dependence rates among those with ALDH2*2. Paradoxically, while around 30% of South Koreans have ALDH2*2, they still maintain both high levels of alcohol consumption and dependence. Therefore, how the negative reactions to alcohol experienced by those with ALDH2*2 interact with the expected effects of alcohol and sensitivity to punishment is of interest. Four hundred and sixty South Korean university students were tested for the ALDH2 gene type and completed alcohol expectancy and sensitivity to reward/punishment measures. The results indicated that there are different predictors of alcohol consumption depending on gene type, with ALDH2*2 heavy drinkers exhibiting lower levels of SP and higher levels of tension reduction expectancy. These findings suggest that ALDH2*2 plays a central role in differences in motivation for alcohol consumption among South Koreans.
