Due to Rapid Human DNA Degradation Rare Diseases Are Increasing in Frequency
https://www.munichre.com/topics-online/en/2015/02/rare-diseasesBy 2020, about 10% of people will carry at least one disease-causing genetic mutation. In Europe, this is about 42 million people, over 400 million in Asia and some 52 million in North America. There are so many diseases caused by genetic mutations that the medical industry is not able to handle them all. When a certain genetic disease is affected by a relatively small proportion of the population, pharmaceutical companies are not economically viable to develop treatment for rare illness. This causes problems for society.
The total number of disease-causing genetic mutations in the human DNA at population level is 214,158. Annual increase was more than 20,000.
