Frequencies of VNTRs in <i>SLC6A3</i> and <i>MAOA</i> as well as common variants rs17689918 in <i>CRHR1</i>, rs1360780 in <i>FKBP5</i>, rs53576 in <i>OXTR</i>, rs12720071 and rs806377 in <i>CNR1</i>, rs4311 in <i>ACE</i>, rs1800497 in <i>ANKK1</i>, and rs7412 and rs429358 in <i>APOE</i> did not differ among the groups.<h4>Conclusions</h4>a generation born during a period of prolonged destructive events may differ from the rest of the gene pool of the population in some variants associated with personality traits or stress-related disorders. This evidence concerns the gene CNR1 and stress-related disorder.
