Here, on good authority, I have a documentary proof of the fact that Lech Kaczynski had a genetic disorder, which is fragile X syndrome (FXS), characterized by hereditary mental retardation, signs of which clearly has his brother Jaroslaw as well.
As far as I could ascertain it, the main symptom of the disease is an intellectual disability of varying severity (IQ 13-75) in combination with behavioral, facial and somatic abnormalities. Symptom appears variably but mental retardation (memory disorders, learning difficulties, low IQ, speech disorders, inadequate perception of reality, unsociable demeanour) is the most common sign. Most patients have psychopathic disturbances in form of high excitability, uncontrolled manifestation of panic and aggression.
I sent the results of examination of Lech Kaczynski's genetic material to the published addresses of Polish specialists in the field of molecular genetics Donata Kurpas and Marcin Wozniak, asking them for expert evaluation and comments on the assumption of presence of the disease in Jaroslaw Kaczynski's genes, but there is still no answer. Therefore, to my regret, anyhow more professional description of the syndrome and its intensity in Jaroslaw Kaczynski cannot be given.
In any case, the appearance and inappropriate behavior of politician that unfortunately has currently significant influence in Poland, indicates to the presence of serious medical problems.
