Association between OPRK rs643799 and variability in thermal skin pain thresholds (univariate analysis). Carriers of OPRK rs643799C allele (genotype CC / CT, n=18, 47.9+/−2.7°C) have lower thermal pain thresholds than non-carriers (genotype TT, n=18, 45.5+/−2.3°C), p=0.009. Line demonstrates mean values.
