Mutation screening of the dopamine D1 receptor gene in Tourette's syndrome and alcohol dependent patients.

We report a single stranded conformational polymorphism (SSCP) analysis of the coding region of the dopamine D1 receptor (DRD1) in Tourette's syndrome (n = 50) and control (n = 50) subjects. Tourette's syndrome populations with comorbidity for attention deficit-hyperactivity disorder (AD-HD) (n = 35) and obsessive compulsive disorder (OCD) (n = 30) were also screened. As a related study, we also screened patients diagnosed with alcohol dependence (n = 72). The present study discovered no DRD1 coding region mutations in any of the Tourette's syndrome or alcohol dependent patients. One silent mutation, a C for a T at Ile49, was discovered in one control subject. The non-polymorphic structure of the DRD1 gene among the Tourette's syndrome, Tourette's syndrome comorbid with AD-HD and OCD and the alcohol dependent populations screened by SSCP suggests that coding region mutations of the DRD1 gene are unlikely to contribute to the inheritance of these disorders.[1]
