the molecular and neurobehavioral functional consequences of BDNF Met66Val polymorphism (rs6265) for more than a decade,143 although its association with ND phenotypes is still relatively weak (Table 2). Combining the susceptibility map results with relevant functional annotations will facilitate determination of variations bearing higher translational values.144 All in all, this map empowers us to sift through existing accomplishments and ponder future research strategies, an approach that may serve as a useful tool for other complex diseases/traits also.
