Some people appear to be born with 'superhero DNA' that cancels out genetic diseases like cystic fibrosis, say researchers.
An international team of scientists studied the DNA of close to 600,000 people, trying to find individuals who carried damaging genetic mutations. But rather than focusing on those who succumbed to illness, they looked at an even smaller sub-group who beat the odds and remained healthy.
Researchers found (lucky) 13 who should have developed debilitating diseases, but did not.
These people were born with a genetic predisposition towards developing serious and debilitating conditions such as cystic fibrosis, but something in their genomes caused them to still be resistant to the illnesses.
However, this is where the tantalising story ends. The scientists were unable to go out and find the lucky 13 because of the consent rules signed when their DNA sample was taken. It means they do not know what is protecting them against disease.
