TY - JOUR PY - 2020// TI - The rs6265 polymorphism of the BDNF gene is related to higher-lethality suicide attempts in the Korean population JO - Psychiatry investigation A1 - Kang, Seung-Gul A1 - Lee, Jong Hun A1 - Lee, Kwanghun A1 - Kim, Hee-Cheol A1 - Seo, Wan Seok A1 - Won, Seunghee SP - ePub EP - ePub VL - ePub IS - ePub N2 - OBJECTIVE: Since the risk of suicide cannot be predicted by clinical symptoms alone, and suicide is known to have a genetic component, the discovery of genetic markers that can predict the lethality of suicide attempts is a clinically important topic. There have been many studies aiming to determine whether the rs6265 polymorphism of the BDNF gene is associated with suicidality; however, the results have been mixed, and there have been few studies investigating the relationship between this polymorphism and suicide attempt lethality.

METHODS: We assessed suicide lethality in 258 individuals who had attempted suicide using the relative risk ratio (RRR) scale and by genotyping the rs6265 polymorphism of the BDNF gene.

RESULTS: The RRR score for suicide attempts was higher in subjects with Met/Val and Val/Val genotypes than in that with a Met/Met genotype (p=0.015). The RRR score for suicide attempts was also higher in Val allele carriers (Met/Val+Val/Val) than in Met/Met homozygotes (p=0.006).

CONCLUSION: This study demonstrates the possibility that the rs6265 polymorphism of the BDNF gene could be used as a genetic marker to predict the lethality of suicide attempts, but more replication studies are needed for the application of this result in clinical practice.
