Investigators from the Tuberous Sclerosis Complex (TSC) Autism Center of Excellence Research conducted two concurrent prospective longitudinal studies to analyze the timing and pattern of clinical presenting symptoms of TSC in infants to facilitate earlier diagnosis and treatment in this specific population. [1]. Early diagnosis of tuberous sclerosis complex: a race against time. There were 130 participants that met diagnostic criteria for TSC. It occurs in about one in every 6,000 newborns, and its symptoms may show up in the first year of life in many patients. Infantile spasms (IS) were also more common with TSC2 (68%) compared to NMI (42%) and TSC1 mutations (7%). What Is Tuberous Sclerosis? Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. Tuberous sclerosis complex is a congenital disorder, although age at diagnosis may range from birth to adulthood. Tuberous sclerosis, also known as tuberous sclerosis complex, is a rare genetic condition that causes mainly non-cancerous (benign) tumours to develop in different parts of the body. System involvement, severity of clinical symptoms and the response to treatment are age-dependent and heterogeneous. PubMedCentral CrossRef PubMed Google Scholar. Brain MRI, echocardiography, skin examination and genetic testing should be performed early in every patient suspected of having TSC. [PubMed], Słowińska, M Jóźwiak, S Peron, A Borkowska, J Chmielewski, D Sadowski, K et al. The importance of earlier diagnosis is related to the high frequency of epilepsy in this population, and early treatment of seizures is essential [1–3].
