Abstract:
Many risk factors have been identified for suicide behavior and although a role for cytokines has been suggested in specific psychiatric conditions and suicide behavior, this role is not well-defined. Since some polymorphisms can alter the expression of cytokines, in this study we attempted to assess the role of TGF-β1 codon 10 (T/C) polymorphisms (rs1982073) in suicide behavior. A total of 145 individuals with suicide behavior as well as 200 control participants (without any history of suicide behavior) were included in the study. TGF-β1 codon 10 polymorphism was determined using allele-specific oligonucleotide polymerase chain reaction. Our results demonstrated that the TGF-β1 codon 10 T/T genotype was significantly more prevalent in individuals with suicide behavior (41.7%), in comparison with the controls (27%). The findings of this study demonstrated an association between TGF-β1 (codon 10) T/C polymorphisms and suicide behavior.
