Informations about the disease
Tuberous sclerosis is a multi-system disease with conspicuous skin involvement already in early childhood. Besides facial angiofibromas, hypomelanotic maculae, fibrous forehead plaques, there are also ungual fibromas. Common non-dermatological manifestations affect the central nervous system, heart, kidneys, lungs, abdominal organs, retina and bones. The main characteristics of the disease are benign hamartomas, which develop in the organs and differ in number and size. The tuberous sclerosis complex is inherited autosomal dominantly, the penetrance and expressivity are highly variable and range from mild dermatological symptoms with normal life expectancy to persistent epilepsy and severe intellectual deficit. The diagnostic yield when examining the TSC1 and TSC2 genes is 75-90%. An inconspicuous genetic finding does not therefore mean that the suspected clinical diagnosis can be excluded with certainty.
