Some examples of orphan diseases include: Neurological disorders (such as multiple sclerosis), clotting problems (such as hemophilia) and lung conditions (such as cystic fibrosis) are some of the most common orphan diseases. In fact, about 8 percent of the population suffers from these diseases.ДЁ0 percent of these diseases are of genetic origin and to a lesser extent immune, neoplastic (abnormal cell growth) or infectious diseases. To date, science has discovered 7,000 orphan diseases, but there are still hidden diseases, patients who do not know they have them, and pending diagnoses. In other countries, it is 1 out of 5,000 people. In Europe, in order to be considered as вЂњorphanвЂќ, these diseases shall affect 1 out of 2,000 people. Moreover, they affect a small number of people. Usually these types of conditions are chronic and progressive, that is to say that they are of long duration and slow progression, and the first signs may be seen at birth or childhood. Indeed, these diseases will affect the health, have a unique pattern of symptoms and a single treatment.

However, when two people carry the same genetic disease, their children may inherit this mutation and develop the disease.

These unexplainable diseases are now known as rare, orphan or forgotten diseases and thanks to science and to the research and development industry, they are no longer an inexplicable phenomenon but have a name, an explanation, a treatment and even a cure.ДЄll humans are carriers of at least eight genetic diseases or enigmatic conditions (mutations), which present no symptoms or signs. DoctorsвЂ™ responses were limited, and diagnoses ended up with supernatural or superstitious explanations. Just a few decades ago, some diseases were unexplainable.
