Biomedicine & Pharmacotherapy, 1997 Besides familial Alzheimer's disease (AD), the genetic susceptibility has also been found in sporadic cases of AD, mostly related to the apolipoprotein E polymorphism. The penetrance of AD is determined by age and probably by environmental exposure. Gene-environment interaction of a disease can be examined through studies of twins.
