| Abstract | Suicidal behavior is a serious public health problem which is partly heritable. Identifying the genes and the neurobiologic pathways relevant to suicidal behavior is important for preventative strategies. One family-based study reported an association between sodium channel voltage gated type VIII alpha (SCN8A) and suicidal behavior. In the present study, we aimed to search forSCN8Apolymorphisms conferring genetic susceptibility to suicide in the Chinese population. A total of 626 subjects was recruited for the study, including 297 suicide attempters and 329 non-attempters from Shanghai, China. We conducted a case-control association analysis of five SNPs (rs10506302, rs1601012, rs4762004, rs12581041, rs17126078) within the region ofSCN8Agene. we found that two genetic polymorphisms showed statistically significant differences between cases and controls (rs1601012, P=0.004; rs12581041, P=0.01). Moreover, no haplotypes were significantly associated with suicidal behavior in psychiatric disorders after the false discovery rate (FDR) correction. In the analysis ofschizophreniasubgroup, three genetic polymorphisms showed statistically significant differences between cases and controls (rs10506302, P=0.024; rs1601012, P=0.004; rs12581041, P=0.004). Our findings suggest that theSCN8Agene may be involved in the susceptibility to suicidal behavior among psychiatric disorder patients in the Han Chinese population. |
