A single nucleotide polymorphism (SNP; C-1021T) in the DbetaH gene is relevant to paranoia associated with disulfiram pharmacotherapy for cocaine addiction.
Recently, two polymorphisms (DBH5'-Ins/del and DBH 444 g/a) of the Dopamine Beta Hydroxylase (DBH) gene were isolated, and one haplotype (Del-a) was found to be associated with low DBH activity and cocaine-induced paranoia.

As predicted, the low-DbetaH-associated haplotype, Del-a, was significantly more frequent (P = 0.0003) in subjects endorsing cocaine-induced paranoia (n = 29) than in those denying it (n = 16).
