PG - 186-90 LID - 10.1111/j.1601-5215.2009.00401.x [doi] AB - BACKGROUND: Val66Met polymorphism in the brain-derived neurotrophic factor (BDNF) gene has been suggested to be associated with major depressive disorder (MDD). There were a few reports of the relationship between the variant and late-onset depression (LOD) in Chinese Han population. OBJECTIVE: To investigate the relationship among BDNF Val66Met gene variants, BDNF plasma level and LOD. METHODS: Chinese Han patients with LOD (n = 99) and control subjects (n = 110) were assessed for BDNF Val66Met gene polymorphism. BDNF plasma level was tested only in LOD. RESULTS: There were no significant differences in genotypes and allele frequencies between cases and controls (p = 0.744 and p = 0.845, respectively). Plasma BDNF level also did not show significant differences in three genotypes in LOD (p = 0.860). CONCLUSION: The Val66Met polymorphism in BDNF gene may not confer susceptibility to LOD in Chinese Han population.
