Final week, medical doctors announced that a UK lady, Jo Cameron, barely perceives discomfort due to a mutation in a previously undiscovered gene accountable for controlling anandamide, an endocannabinoid related to THC.
Medical doctors initially noticed anything uncommon when Cameron, 71, visited for a poor hip. X-rays revealed important bone deterioration, which ought to have brought on outstanding amounts of discomfort.
“I’d not had a twinge,” Cameron told The Guardian. “They couldn’t think it.”
Just after a second surgery involving osteoarthritis — one more bone-deteriorating situation — in her hands, medical doctors realized she seemed fairly unaffected by discomfort. Cameron calls for small to no discomfort drugs either for her chronic ailments or for post-surgery recoveries.
When medical doctors investigated additional by seeking at her genes, they found two mutations involved in the regulation of anandamide. Anandamide, which comes from the Sanskrit ananda which means “supreme joy,” was the initially endocannabinoid found.
Endocannabinoids are marijuana-like compounds created by the human physique (from endo- which means “within” and –cannabinoid which means “weed-like”). Investigation shows anandamide directs feelings of hunger, memory formation, social bonding, and discomfort perception.
The Israeli pot scientist, Raphael Mechoulam, Ph.D., believes anandamide is the body’s version of THC, the intoxicating chemical located in cannabis.
The initially mutation found in Cameron, a pretty frequent 1, reduces the quantity of FAAH created in the brain. FAAH, or fatty acid amide hydrolase, is an enzyme that breaks down anandamide. If the physique tends to make much less FAAH, it experiences a construct-up of anandamide.
Cameron’s all-natural anandamide levels are twice as higher as the typical particular person.
The second mutation is distinctive, on the other hand. Spotted in a nearby gene lately dubbed FAAH-OUT, Cameron’s variant is missing half its code. Scientists think FAAH-OUT tunes down the FAAH enzyme’s activity.
The excess anandamide swirling about Cameron’s nervous method exhibits effects related to smoking weed. Medical doctors say along with feeling no discomfort, she does not practical experience depression or anxiety, either. She heals rapidly, thinking of her age. She also tends to be much more forgetful. Sound familiar?
Despite the fact that Cameron’s genes virtually make her a weeded superhero, never ever feeling discomfort has its drawbacks. She usually cuts or burns herself even though going about her each day chores, unaware of the harm till some other cue alerts her (such as smelling burning flesh when she accidentally leans on the stove).
Regardless of the dangers, scientists hope they can use this new facts to much better treat sufferers in the future.
“There’s an awful lot we can discover from her.  Once we realize how the new gene operates, we can assume about gene therapies that mimic the effects we see in her,” stated James Cox, 1 of the scientists who analyzed Cameron’s genes. “There are millions of persons living in discomfort and we surely want new analgesics. Sufferers like this can give us genuine insights into the discomfort method.”
