Man is a living being and the manifestation of immanence in society is the main cause of diseases. The true origin of the disease is the result of environmental exposure.
If we try to identify the causes of diseases by identifying factors that do not depend on us, this may lead to the erroneous conclusion that the diagnostic search is futile. Of course, there is a relationship between heredity and acquired diseases. However, the role of hereditary factors should not be neutralized. Most hereditary diseases and syndromes manifest themselves at a young age, often long before a person enters independent life. Sooner or later, nature reveals its patterns, and these patterns make it possible to suggest a diagnosis, starting from the first months of the disease. This allows early diagnosis to save lives or improve the effectiveness of treatment.
