NCT01293994

Brief Summary

The investigators will be collecting saliva DNA samples from chronic back pain patients. The investigators hope to find candidate genes associated with response to opioid medication by correlating molecular genetics data with pain measurement and opioid responsiveness data including opioid hyperalgesia and opioid analgesic tolerance.

Biospecimen

Retention: SAMPLES WITH DNA

Saliva biospecimen collection will be performed via mail or in person. The PI will send participants a letter informing them of the opportunity to participate in a study of genetic variation influencing pain and opioid responsiveness phenotypes. If participants agree to provide a saliva biospecimen and to participate in the study, an informed consent letter and an Oragene™ DNA Self-Collection Kit, in disk format OG-250 (DNA Genotek, Inc., Ottawa, Ontario, Canada) will be sent to the participant by the PI. According to the manufacturer instructions, participants will provide a 2 ml saliva sample, which will be preserved using the reagents provided within the Oragene™ kit. Saliva samples are considered stable at room temperature for 5 years by Oragene™.
