}}[[rs7294919]], showed a particularly strong link to a reduced hippocampus volume, suggesting that this gene is very important to hippocampus development or health. No associations for brain volume, but they did discover that intracranial volume was significantly associated with two loci: [[rs4273712]], a known height locus on chromosome 6q22, and [[rs9915547]], tagging the inversion on chromosome 17q21.
