Genetic linkage to nicotine dependence was examined in families from New Zealand, and regions on chromosomes 2, 4, 10, 16, 17 and 18 yielded small but positive lod scores [39]. These findings were not replicated in a study on families from the United States. All these studies were relatively small and it is probable they did not provide sufficient power to detect genes of small effect or those which influence risk in only a proportion of the families.

Research into the risk factors for Cluster A personality disorders has focused on genetic factors. In particular, many researchers have looked for a shared genetic linkage between these disorders and schizophrenia. Only schizotypal personality appears to be genetically linked to schizophrenia. It may be that STPD exists on a biological continuum with schizophrenia. In other words, STPD could theoretically be a far milder variant of Axis I schizophrenia. There is less evidence linking PPD or SPD to schizophrenia nevertheless, certain characteristic symptoms of these other disorders also overlap with schizophrenia.
