Most theories are related to childhood and parenting, but overall the available evidence points to no one definitive cause of BPD. Instead, a combination of genetic, developmental, neurobiological and social factors, evidently contribute to the development of BPD.
Family studies suggest that first-degree relatives of borderlines are several times more likely to show signs of a personality disorder, especially BPD, than the general public. It is unlikely that one gene contributes to BPD; instead, like most medical disorders, many chromosomaloci are activated or subdued, probably influenced by environmental factors, in the development of BPD.
