  1. The mean ± SD of the sum of borderline symptoms (BPD score) from the self-report SCID-II Screen questionnaire are presented for the different genotype groups. Where it is indicated, in the second set of univariate ANOVAs rare homozygote genotypes (n < 5) or literature-based genotypes were grouped together with the heterozygotes for the fixed factor; sex and age were used as covariates.
  2. * At the DAT1 VNTR one 10/11 and one 10/12 sample were grouped together with the 10/10 (9-allele absent) genotype group.
