TSC causes the growth of non-malignant tumours to form in vital organs. TUBEROUS SCLEROSISThis child demonstrates thetypical features of tuberoussclerosis (TS) together withsome less common manifestationsof the disease. These genes are involved in regulating cell growth, and the mutations lead to uncontrolled growth and multiple tumors throughout the body. They are usually benign (non-cancerous). While the tumors typically are non-cancerous, they can cause serious health complications if left untreated. The estimated prevalence ranges from one in . 6000 to one in 12 000 (1), and approximately two-thirds of the cases are sporadic (2). In patients with dyskeratosis congenita, nail changes are the first findings to be observed typically presenting between 5 and 13 years of age.

Oxford: Oxford University Press; 1999. Tuberous sclerosis (TS) is an autosomal dominant inherited neurocutaneous syndrome characterized by a variety of hamartomatous lesions in various organs. [] TSC1 and TSC2 genes encode for hamartin (TSC1) and tuberin (TSC2) form a regulatory complex responsible for limiting the activity of an important intracellular regulator of cell growth and metabolism, known as mammalian target of rapamycin complex 1 (mTORC1). Keywords: Mild cognitive impairment; Nail diseases; Tuberous sclerosis s INTRODUCTION Onychogryphosis is a nail deformity characterized by an opaque, yellowish-brown nail plate that is distorted, grossly thickened, elon- gated and partly curved like a ram’s horn.1 Possible causes of ony-chogryphosis include continuous pressure and friction on the toe-nails due to improper footwear, … Tuberous sclerosis complex (TSC) is characterized by the growth of benign tumors throughout the body, including in the heart, brain, and kidneys.
