title: ALDH2*2 Allele is a Negative Risk Factor for Cerebral Infarction in Chinese Women.
abstract: Unlike its reported role in the cardiovascular diseases, little information is available for mitochondrial aldehyde dehydrogenase 2 (ALDH2) in the cerebrovascular function. We investigated the different effects of ALDH2 genotypes on the risk of cerebral infarction between the genders, because different genders had different smoking and/or dinking status which are also risk factors for cerebral infarction. 247 healthy Chinese Han people (controls, group 1), 287 Chinese Han male patients with cerebral infarction (group 2), and 82 Chinese Han female patients with cerebral infarction (group 3) were involved in this study. The frequencies of the ALDH2*2 allele in group 3 were significantly higher than those in other groups (with P = 0.001 and P = 0.002, respectively). The difference of ALDH2*2 allele frequency between group 1 and group 2 was not significant (P = 0.652). After adjustment for smoking and drinking status, the male patients without smoking or drinking status (group 4) had higher ALDH2*2 allele frequency than group 1, but the difference was still not significant (P = 0.139). Thus, we conclude that ALDH2*2 allele may be a significant negative risk factor for cerebral infarction in Chinese women [odds ratio (OR) = 2.207, 95% CI 1.416-3.439]. But for Chinese male patients, the negative effects of ALDH2*2 allele on cerebral infarction which might be concealed by other risk factors were not significant.
