Scientists Find Genetic Mutation That Makes Women Feel No Pain (theguardian.com) 106

An anonymous reader quotes a report from The Guardian: Doctors have identified a new mutation in a woman who is barely able to feel pain or stress after a surgeon who was baffled by her recovery from an operation referred her for genetic testing. Jo Cameron, 71, has a mutation in a previously unknown gene which scientists believe must play a major role in pain signaling, mood and memory. The discovery has boosted hopes of new treatments for chronic pain which affects millions of people globally.

In a case report published on Thursday in the British Journal of Anaesthesia, the UCL team describe how they delved into Cameron's DNA to see what makes her so unusual. They found two notable mutations. Together, they suppress pain and anxiety, while boosting happiness and, apparently, forgetfulness and wound healing. The first mutation the scientists spotted is common in the general population. It dampens down the activity of a gene called FAAH. The gene makes an enzyme that breaks down anandamide, a chemical in the body that is central to pain sensation, mood and memory. Anandamide works in a similar way to the active ingredients of cannabis. The less it is broken down, the more its analgesic and other effects are felt.

The second mutation was a missing chunk of DNA that mystified scientists at first. Further analysis showed that the "deletion" chopped the front off a nearby, previously unknown gene the scientists named FAAH-OUT. The researchers think this new gene works like a volume control on the FAAH gene. Disable it with a mutation like Cameron has and FAAH falls silent. The upshot is that anandamide, a natural cannabinoid, builds up in the system. Cameron has twice as much anandamide as those in the general population.

      Right, but, while there are more reasons for humanity's being "good" at making weapons, the major reason for things staying that way in the 21st century is that the operating system humanity is continuing to live by is based on another thing humanity is good at, too: working for the profits of a few, instead of people's needs.

    Isn't pain necessary? The woman cuts her foot while walking on the beach and doesn't feel anything. She is heavily bleeding, and keeps smiling because she doesn't feel stress either.
    • Yes, this woman has said she only noticed when she burned herself by smelling smoke, and he let an arthritic hip get to a very bad state because she hadn't noticed the pain.

      • A friend of mine was deeply depressed and tried to commit suicide.
        They found her and put her a hospital, actually a psychiatric one, but stupid as they are they did not fixate her.
        So when she woke up, she took the plastic knife from the neighbour bed and tried to cut her wrist. She damaged her wrist so much (sinew and nerves) that the hand got useless. She however got healed and is happy again (that happened over 20 years ago).

        • This particular case of genetics is not a matter of not feeling anything or being numb. Tons of people lose sensation and can't feel pain because of nerve damage. This woman does feel things, she just doesn't experience the pain aspect of it. She doesn't even get depressed. This is an unusual phenomena.

          It's like the difference between someone who's deaf and doesn't feel the pain from listening to Justin Bieber on a loop, and a person who listens to that and thinks it's a lovely sound.

      Yes, she burns herself quite often while cooking and doesn't notice until the smell of searing flesh reaches her nostrils. In fact she only found out about it when she went for an x-ray and they found she had severe hip problems but hadn't noticed due to lack of pain.

      Quite how they didn't realize when she apparently experienced no pain during childbirth is a bit of a mystery.

        She's 71. The medical establishment especially back then didn't have a reputation for paying the blindest bit of attention to well just about anything to do with women.

        • Or, you know, they almost certainly DID notice, and this is just the usual crappy reporting.

          It's not as if her condition is unique; there are plenty of other documented cases of people who couldn't feel pain. She's just the first one to have her DNA sequenced in an attempt to figure out why.

    • It's not a binary. Pain and anxiety are both good in a way, but balance is critical. Too much pain and stress, and you become unable to function even in simple low-stress/low-pain situations. Not enough pain and stress, and you become unable to function in risky or critical situations. Most people fall within the functional spectrum, but quite a few (especially these days when work is becoming more and more stressful) get serious problems. If you've seen a high-strung girl in school that gets ulcers at the

    The sources say that a specific woman has been identified as having a genetic mutation that affects her pain response and (from the Guardian):

    "Cameron’s mother felt pain normally, as does her daughter. But her son, who carries the second and more important mutation, has a dulled sense of pain. He never takes painkillers and frequently scalds his mouth with hot drinks and food. Scientists suspect that Cameron’s father may have passed the mutation on to her."

    Slashdot mutates that in its headline about something that specifically makes women (plural) feel no pain.

      This is an exciting line of research. If they can find a way to dull pain permanently it could help a lot of people with chronic pain. It's hard to describe to people who don't have it just had debilitating it can be. Even relatively low levels of pain have a huge effect if they are constant.

        Yup. Although pain can be a sign to the person that they need to rest the affected part, the chronic stuff gets a life of it's own. And opioids surely aren't the solution other than in the very short term.
