Abstract

There is evidence that genetic factors influence the probability of comorbidity of tobacco use disorder (TUD) with mood disorders. This study was carried out to examine whether both TUD and mood disorders are associated with genetic biomarkers particularly paraoxonase 1 (PON1) status, polymorphisms of glutathione S-transferases (GSTs), such as GSTM1 and GSTT1, and the STIn 2 polymorphism of the serotonin transporter. PON1 status (Q192R polymorphism and PON1 plasmatic activity), GSTM1, GSTT1, and STin.2 genotypes and alleles were assayed in 4 mutually exclusive study groups, i.e., comorbid mood disorder and TUD (n=95); TUD without mood disorders (n=90); mood disorders but no TUD (n=62); and c..
