Your DNA is not your destiny, nor a good predictor of your health – Study

I can’t tell you how happy I was to learn this. I have had friends who threw up their hands when it came to living a healthy life. They said they failed because of their ‘bad genes.’ I always felt this was a cop out and total denial of responsibility and now it seems I was correct. Take responsibility.

In most cases, your genes have less than five percent to do with your risk of developing a particular disease, according to new research by University of Alberta scientists.

The study also highlights some notable exceptions, including Crohn’s disease, celiac disease, and macular degeneration, which have a genetic contribution of approximately 40 to 50 per cent. The image is in the public domain.

In the largest meta-analysis ever conducted, scientists have examined two decades of data from studies that examine the relationships between common gene mutations, also known as single nucleotide polymorphisms (SNPs), and different diseases and conditions. And the results show that the links between most human diseases and genetics are shaky at best.

“Simply put, DNA is not your destiny, and SNPs are duds for disease prediction,” said David Wishart, professor in the University of Alberta’s Department of Biological Sciences and the Department of Computing Science and co-author on the study. “The vast majority of diseases, including many cancers, diabetes, and Alzheimer’s disease, have a genetic contribution of 5 to 10 percent at best.” Continue reading
