The mapping of human DNA is already a reality, and now research is also directed at changing parts of the genetic code, in order to correct problems or alter the functioning of certain structures of the organism. It sounds like a science fiction movie, but it's not. You can read more about CRISPR here.

In the US, there are companies that, at affordable prices, offer simple genetic analysis related to superficial issues. This requires you to mail your genetic material, and after analysis the laboratory provides the information you have requested. NBC Chicago reporter Phil Rogers decided to test five of these companies by sending DNA samples from his dog, the lab Bailey.

It's not Bailey, but it could be

Dogs have many similarities to us, including DNA, but a simple analysis would probably be able to differentiate each other. Right? This is not quite what happened. Most companies analyzed the animal's saliva and accused the genetic material of being illegible, but one of them provided the results normally.

Orig3n

Orig3n provides three testing options, one called a superhero, to determine your strengths (intelligence, strength, speed), another to find out which foods are best suited for your genetic profile, and the last one to analyze how your genes affect your athletic potential.

Bailey underwent the first, and the results were not as surprising as this: her muscle strength was effective in fast movements, boxing or basketball was recommended, and her cardiorespiratory ability was conducive to long cycling or running. Finally, it was suggested that Bailey exercise with the help of a personal trainer.

The company already had suspected irregularities and was investigated by the US government for selling tests without proper laboratory certifications. Upon receipt of the results, Rogers attempted to contact Orig3n but received no feedback.

Test reliability

According to University of Chicago Hospital Genetics Counsel Jessica Stoll, "Most genetic tests are still a gray area, and there is always a possibility of incorrect results." She also says that tests such as those made by the report do not present any risk, because the results do not directly influence people's health. What worries her are tests that pinpoint predispositions to serious illnesses like Parkinson's or Alzheimer's.

To know better about the possibility of developing these diseases, in addition to a really accurate genetic examination, it is necessary to survey the entire medical history of the patient and his family. So if you have the opportunity to do such a test, consider these technical limitations we currently have.
