New research claims that some people are born with what has been termed a Super hero DNA which is known to eliminate diseases such as cystic fibrosis.
The researchers studied about 600,000 people who had genetic mutations linked to diseases and found that about 2.2% of the people examined who should have developed genetic diseases, did not. The eight diseases which should have been developed by the patients were cystic fibrosis, Smith-Lemli-Opitz syndrome, familial dysautonomia, epidermolysis bullosa simplex, Pfeiffer syndrome, autoimmune polyendocrinopathy syndrome, acampomelic campomelic dysplasia and atelosteogenesis.
While mutations in the DNA cause diseases, these group of researchers were out to find the opposite — what keeps people healthy.
Dr Eric Schadt, co-founder of the Resilience Project from the Icahn School of Medicine at Mount Sinai Hospital in New York said, “Millions of years of evolution have produced far more protective mechanisms than we currently understand
“Most genomic studies focus on finding the cause of a disease, but we see tremendous opportunity in figuring out what keeps people healthy.”
On the accuracy of the 13 people who seemed immune to these diseases, the researchers believed that the symptoms of the disease are so acute that it is impossible for their health history to not have any records of it if they had truly developed the disease.
Although the study was indeed aimed at studying the healthy (those with super hero DNA ) to see what really protects them from from diseases, the researchers were unable to. They had signed some consent papers upon getting the DNA sample, this meant they were unable to contact the 13 people.
“Because of the inability to confirm the source or validity of the variants and the inability to recontact the individuals, this paper does not constitute a proof of principle,” Dr Ada Hamosh, from Johns Hopkins University, argued.
The report was first published in Nature Biotechnology .
