Chunk #3 — Summary

Source: Association analysis between polymorphisms in the dopamine D3 receptor (DRD3) gene and cocaine dependence.
Embedded: yes

Text

Our results do not support an association of the DRD3 gene with cocaine dependence; however, additional studies using larger samples and different populations are necessary to conclusively rule out DRD3 as a contributing factor in the etiology of cocaine dependence.
