Patients participating in START will be offered the opportunity to volunteer for a genetics study that has the primary objective of genotyping patients for exploratory analyses.  Genomic DNA from blood samples sent to the NIDA Genetics Repository will be extracted and saved for future study.  Investigators at the University of Pennsylvania will study the frequency of gene variants that have primarily been associated with addiction, while the Medical University of South Carolina researchers will examine the relationship between treatment drug plasma concentrations and gene variants associated with drug disposition and transport.

Primary Findings

Study findings suggest that rs581111 and rs52920 may be useful when considering treatment options for female opioid addicts; however, confirmation in an independent sample is warranted.
