Abstract

We report two novel polymorphisms and a rare deletion variant in the human dopamine D4 receptor gene. The two polymorphisms are characterized by single base pair substitutions, namely a G→C transversion changing codon 11 from GGG (encoding Gly) to CGG (encoding Arg) and a C→T transition in position −11 upstream from the start codon. The Arg11 variant occurs at a frequency of about 1% and the C→T transition at a frequency of about 7% in German control subjects (n= 148). Allele frequencies observed in patients suffering from schizophrenia (n = 256) and bipolar affective disorder (n = 99) were similar. The deletion variant is characterized by a 21 bp deletion affecting codons 36 to 42 coding for amino acids Ala-Ala-Leu-Val-Gly-Gly-Val located in the first transmembrane domain of the dopamine D4 receptor. The mutation was identified in a single individual suffering from obsessive-compulsive disorder and panic disorder. We were unable to detect the deletion in patients with schizophrenia and bipolar affective disorder, nor in healthy controls.
