Rare genetic mutation: No pain (Video)

Letisia Marsielli, 52, associate professor of the University of Siena in Italy, has inherited from her 78-year-old mother a rare genetic mutation, which has been passed on to three children -- two boys aged 24 and 21 -- and the 16-year-old daughter.
All of them, find “Z FHX2” appears in a different form, causing Letizia and her relatives to feel no pain.
The confessions of members of this family are surprising. One of them may pull his shoulder out and not feel it at all, another may ride on a bicycle without realizing that his leg is broken.
One of the boys has repressed his career in a football field, but he has continued to play. Nor is there any problem with boiling water, which does not give him the sense of skin burning.
The Martian family members affected by this syndrome, pain, or pain does not appear at all, or feel light for a moment, and then disappear completely.
After studying the genoma of each of the family members, researchers have been able to reveal the mystery that will afflict three generations. Mutation makes them feel no physical pain, but a normal density of intrapidermic nerve fibers is observed in all.
That means the nerves are all there. They simply do not function properly”, experts explain. To illustrate more clearly the role of genetic mutation, scientists eliminated “Z FHX2” from some lab cables that were unable to perceive the pain, then passed the mutation on to another cavia group, saw that they became insensitive to heat.
