Borderline personality disorder (BPD) tends to “run in families.” Twin and twin family studies show that BPD is moderately heritable, with some evidence for nonadditive gene action. BPD co-occurs with Axis I and other Axis II disorders, as well as with a certain profile of normal personality traits. Multivariate twin (family) studies have shown that these phenotypic associations are partly due to genetic associations, and this is observed most strongly for BPD and neuroticism. Candidate gene-finding studies for BPD suggest the possible role of genes in the serotonergic and dopaminergic system, but this needs to be confirmed in larger genome-wide studies. Future studies will complement the knowledge described in this chapter to enable us to move toward a comprehensive model of the development of BPD in which biological and environmental influences on BPD are integrated. |
