When patients do not meet these criteria, they are sometimes referred to as manifesting a forme fruste of the condition. 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. The term Tuberous Sclerosis is derived from the word ‘tuber’ referring to nodular growth pattern and ‘sclerosis’ which refers to calcification of these tumours with age. 1 The diagnosis is made clinically and based on the major and minor criteria outlined in the Table. The symptoms however vary from person to person, depending on where the tumors are growing. Spontaneous mutations account for 50-86% of cases 3, with the remainder inherited as an autosomal dominant condition. Areas of skin containing less pigment than surrounding skin.

Performed at diagnosis if cardiac symptoms occur, and as indicated for follow-up of cardiac dysfunction each 1 to 3 years in asymptomatic individuals until regression of cardiac rhabdomyomas are documented.
