The Val66Met single nucleotide polymorphism (SNP) of the BDNF gene (rs6265) has been studied extensively in the context of psychiatric disorder susceptibility, given it results in diminished activity-dependent BDNF secretion and aberrant trophic function, and has been suggested as a putative locus of risk for anxiety and affective disorders [1, 2, 6]. This evidence concerns the gene BDNF and psychiatric disorder.
