Screening the dopamine D1 receptor gene in 131 schizophrenics and eight alcoholics: identification of polymorphisms but lack of functionally significant sequence changes.

Abstract excerpt

To determine whether mutations in the D1 dopamine receptor (D1 DR) gene are associated with schizophrenia, the coding sequence was examined in 106 Caucasian, 11 African-American, 8 Asian, and 6 Native American patients. Approximately 350 kb of genomic sequence was screened by dideoxy fingerprinting, a method related to single strand conformational polymorphism (SSCP) analysis that detects virtually 100% of...
