Chronic Pain Could Be Genetic
the MPR take:
Chronic pain can be difficult to diagnose and treat due to the range of causes, but genetics may be a significant factor in developing this condition. In a study published in the journal Pain, over 8,000 sets of identical and non-identical twins were analyzed for chronic pain conditions including dry eye disease, irritable bowel syndrome, musculoskeletal pain, and pelvic pain. The conditions were common in identical twin pains, who share the same DNA vs. fraternal twins who do not. Although environmental factors likely also play a role in these conditions, the researchers believe that genetics could account for the risk of developing chronic pain by up to two-thirds.
Four common chronic pain conditions share a genetic element, suggesting they could - at least in part - be inherited diseases, say UK researchers. The study of more than 8,000 sets of twins found the ailments were common in identical pairs sharing the same DNA. While environmental factors probably still play a role in the four conditions, genes could account for as much as two-thirds of someone's chances of developing the disease, they believe.
