ADRA2B deletion variant and enhanced cognitive processing of emotional information: A meta-analytical review

This meta-analytical review examines whether a deletion variant in ADRA2B, a gene that encodes α2B adrenoceptor in the regulation of norepinephrine availability, influences cognitive processing of emotional information in human observers. Using a multilevel modeling approach, this meta-analysis of 16 published studies with a total of 2752 participants showed that ADRA2B deletion variant was significantly associated with enhanced perceptual and...
