✦ Synopsis
Growing evidence suggests that hypertension and Alzheimers disease (AD) may share a common etiology. To evaluate the contribution to AD of genetic factors associated with hypertension, we genotyped clinic and community-based AD cases and controls for polymorphisms within the pancreatic PLA 2 gene and the G protein 3 subunit gene, both of which are located on chromosome 12. Our results do not support an independent association between either of these genes and AD. We further assessed the possibility that either of these genes may interact with the apolipoprotein E gene, a known risk factor for hypertension and AD, on predicting AD. We were unable to find statistical interaction between either the pancreatic PLA 2 or G3 genes and the apolipoprotein E gene on risk for AD. These results do not support a shared genetic etiology between hypertension and AD. Possibly, a clinical association between these diseases could be due to pathophysiologic interactions. Am. J. Med.
