Table 1 TCI temperament scores (mean ±SD) for 99 men and women, stratified by OXTR genotype

From: Sexually dimorphic effects of oxytocin receptor gene (OXTR) variants on Harm Avoidance

OXTR genotype a NS HA RD PS
male T-allele carriers (N=27) 20.0 ±6.1 12.7 ±5.4 15.0 ±3.7 4.4 ±2.1
female T-allele carriers (N=29) 22.3 ±6.1 16.4 ±5.4 16.5 ±2.9 3.4 ±1.9
male non-carriers (N=20) 21.5 ±6.1 11.9 ±4.5 16.5 ±3.6 4.1 ±1.8
female non-carriers (N=21) 22.8 ±4.4 14.5 ±5.0 15.4 ±3.2 4.0 ±1.9

  1. When sex is controlled for and a recessive mode of inheritance is assumed, rs237900 predicts Harm Avoidance in additive and multiplicative regression models.
  2. significance tests refer to log-transformed TCI scores.
  3. a results are shown for rs237900, 2 unreadable ABI trace files.
  4. NS=Novelty Seeking, HA=Harm Avoidance, RD=Reward Dependence, PS=Persistence.
