Gene variants influence size of brain stem and other structures

Researchers identified 48 common genetic variants that appear to play a role in the size of the brainstem and other subcortical structures. Forty of the variants were novel. The findings also revealed 199 genes related to the variants which regulate brain development and susceptibility to neurological disorders.
