The DNA analysis revealed two notable genetic mutations: first, a suppression of the FAAH gene, which normally breaks down a chemical called anandamide in the body. The effects of anandamide are similar to the effects of smoking cannabis, and if it's not broken down, it acts more strongly as a buffer to pain and anxiety.
That mutation is actually relatively common in the general population, but the second one isn't – Cameron was also found to have missing DNA information in a pseudogene the researchers called FAAH-OUT. That means the FAAH gene is more or less completely disabled.
Such a unique combination of genetic tweaks led to Cameron having more than twice the normal level of anandamide in her system. Taken together, these mutations seem to reduce pain and anxiety, while also boosting happiness, forgetfulness, and wound healing. https://www.sciencealert.com/a-woman-who-feels-no-pain-amazes-scientists-and-she-thought-it-was-normal-until-she-was-in-her-60s
