Associated with schizophrenia in a study of Croatians. Due to the limited number and diversity of the studied population, more study is needed to confirm any link. The T allele was associated with an increased risk of schizophrenia. A network of dopaminergic gene variations implicated as risk factors for schizophrenia. Family based association study of pediatric bipolar disorder and the dopamine transporter gene (SLC6A3). Genome-wide and candidate gene association study of cigarette smoking behaviors. Financial and psychological risk attitudes associated with two single nucleotide polymorphisms in the nicotine receptor (CHRNA4) gene. Two loci control tuberculin skin test reactivity in an area hyperendemic for tuberculosis.
