Genetic studies of our population estimate that about 50 percent of the differences in trait sociopathy between individuals are due to small differences in our genes. These small individual differences in our genes are called polymorphisms (poly=many, morph=forms), for many forms of the same gene. It is clear that polymorphisms interact with environmental factors during childhood and adolescence to produce sociopathy. It is also clear that the set of traits that we call sociopathy involves many polymorphisms. There is accumulating evidence that a functional VNTR polymorphism in the promoter region of the monoamine oxidase A (MAO A) gene may give some men a predisposition to sociopathy. …
