Uncovering the Genetic Mutation Behind a Woman's Inability to Feel Pain
Scientists have discovered the genetic mutation that allows Jo Cameron, a 74-year-old grandmother from Scotland, to lead a virtually pain-free life. The mutation, housed in the FAAH-OUT gene, effectively 'turns down' a gene that regulates her pain, mood, and memory. The discovery may hold the key to developing better painkillers and has implications for areas of research such as wound healing and depression.
