The aim of this study was to investigate whether genetic polymorphisms in three dopamine-related genes (the dopamine receptor 2 (DRD2), dopamine receptor 3 (DRD3), and the dopamine transporter (SLC6A3) gene) were associated with delirium.

Without correction for multiple testing, we found a significantly increased allele frequency of a common DRD3 gene variant expressing a serine at position 9 in the extracellular N-terminal part of the receptor protein in 55 alcohol-dependent individuals with delirium (chi 2 = 4.1, df = 1, p = 0.042).
