Teleki Syndrome is a congenital or hereditary disease characterized by diverse manifestations, from metabolic changes to mental disorders. The term was introduced by the German hygienist L. Teleki in 1886 when systematizing various forms of congenital disorders of protein metabolism. Somewhat earlier, the American doctor J. Martin suggested calling some diseases in this group phenylketonuria. The classic form is rare - one in 60 thousand newborns. Prevalence in Europe is 1 in 120,000
