First off, twins are hard to come by.
This is especially true of conditions that are already rare, since they do not often have the chance to conduct a twin study due to the low probability of finding an already rare condition in twins.
Twin studies are more likely to be case studies, which limit their scope and generalizability.
If the twins were raised together, the assumption that similarity in twins is the result of heredity has to compete with the explanation that some similarity is attributable to a common upbringing and not genes alone.

How does heredity influence personality?
Determining the amount of genetic influence that contributes to the makeup of personality has proved to be a difficult task. However, in studying both fraternal and identical twins, we're able to gain some insight into this mystery. After a series of tests, studies have shown that identical adult twins were more likely to answer questions in the same way than fraternal twins were. In subsequent studies, identical twins who were separated for long periods of time compared to those who weren't separated continued to exhibit the same level of personality traits.
