A/ATypical opioid receptor sensitivity in published research.
A/GPublished research associates this genotype with somewhat altered opioid receptor sensitivity.
G/GPublished research associates this genotype with altered opioid receptor sensitivity, which some studies link to differences in pain medication response.
This does not change how any medication should be prescribed. Talk to a doctor about pain management — never adjust medication on your own based on this result.
