L. Oruc et al., ANALYSIS OF THE TYROSINE-HYDROXYLASE AND DOPAMINE D4 RECEPTOR GENES IN A CROATIAN SAMPLE OF BIPOLAR-I AND UNIPOLAR PATIENTS, American journal of medical genetics, 74(2), 1997, pp. 176-178
We selected 83 patients with bipolar disorder type I or unipolar recur
rent major depression and 71 healthy controls for genetic analysis of
the tyrosine hydroxylase and the dopamine D4 receptor gene, No signifi
cant association was found between bipolar disorder type I and unipola
r recurrent major depression and the polymorphisms located near these
genes. Therefore, the hypothesis that the tyrosine hydroxylase and the
dopamine D4 receptor genes may be involved in the etiology of bipolar
disorder and unipolar recurrent major depression is not supported in
our study. (C) 1997 Wiley-Liss, Inc.
