Tuberous sclerosis complex (TSC) is an autosomal dominant disorder and is characterised by the presence of hamartomas in many organs, such as brain, skin, heart, lung, and kidney. It is caused by mutation either TSC1 or TSC2 tumour suppressor gene. The TSC2 gene codes for tuberin and interacts with hamartin Pfam:PF04388 , containing two coiled-coil regions, which have been shown to mediate binding to tuberin. These two proteins function within the same pathway(s) regulating cell cycle, cell growth, adhesion, and vesicular trafficking [1].
