Heritability of Opioid Effects: A Twin Study
Completed · Not applicable · Has a placebo group
Conditions studied: Pain
In brief
Proposed twin study will test to what degree inter-individual differences in pain sensitivity and amount of pain relief in response to opioid therapy are inherited or alternatively, are due to environmental factors. This knowledge is important to guide future studies trying to explain such inter-individual differences. For example, finding that differences are largely due to environmental factors would discourage genomic studies and emphasize epidemiological studies.
