Chemical changes to genes make twins' pain differ
By Ashley Yeager, 12:06 PM February 4, 2014
Genetically identical twins may not experience pain to the same extent because of differences in the way their genes have been chemically modified.
A study of identical twins and of unrelated individuals shows that differences in chemical changes to TRPA1, a gene that directs the production of a temperature-sensing protein, is connected to pain tolerance. The finding, with additional work, may help explain how chemical changes to pain genes influence the way people detect pain could possibly h...
