Healthcare professionals use a checklist of the characteristic features of tuberous sclerosis – such as abnormal areas of skin or tumours in your eyes, brain, heart, lungs or kidneys – to confirm a diagnosis. These genes regulate the growth of cells and mutation of these genes can cause uncontrolled growth and multiplication of the tumours. Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome that occurs in 1 of 6000 children; 85% of cases involve mutations in the TSC1 gene (9q34), which controls the production of hamartin, or the TSC2 gene (16p13.3), which controls the production of tuberin.
