The dopamine D3 receptor gene is of potential interest in the physiopathology of affective disorder because of its expression pattern in brain structures controlling various aspects of behaviour, cognition and emotions.
We conducted a multicenter study of families with mood disorders, to investigate a possible linkage with genes coding for dopamine receptor D2, dopamine receptor D3 and tyrosine hydroxylase (TH).
