[Pain and genetics].
Genetic factors can explain a significant amount of the variance in the perception of pain, sensitivity to painful stimuli and development of chronic pain. Twin studies, association studies and linkage analysis have located DNA sequences and SNPs that may be involved in the regulation of pain. Individual genes have an influence on the reaction to experimental painful stimuli, and certain genes are probably involved in painful clinical conditions. Optimal pain control and counselling of patients may be achievable through research into the genetic mechanisms involved in pain.
