Ash-leaf spots are depigmented areas present in > 90% of patients with tuberous sclerosis complex. Therefore, diagnostic criteria have been developed to aid the diagnosis of tuberous sclerosis. Learn more about our commitment to Global Medical Knowledge. Regardless of severity, most children show continued developmental progress. To be most effective, treatment should be started at the earliest possible opportunity in patients at the highest risk of developing epilepsy.12,13,26,27. Tuberous sclerosis, also known as tuberous sclerosis complex or Bourneville disease, is a neurocutaneous disorder (phakomatosis) characterized by the development of multiple benign tumors of the embryonic ectoderm (e.g. skin, eyes, and nervous system). What is Tuberous Sclerosis Complex (TSC)? (2017). A change in only one copy of a gene causes TSC. The legacy of this great resource continues as the Merck Manual in the US and Canada and the MSD Manual in the remainder of the world. Pathogenesis of infantile spasms: a model based on developmental desynchronization. Tuberous sclerosis complex is a rare genetic disease that causes benign tumors to grow in the brain and other parts of the body, such as the eyes, heart, kidneys, lungs, and skin. Tuberous sclerosis complex (TSC) is a multisystemic, autosomal dominant genetic disorder with complete penetrance, that can evolve with hamartomas in … Clinical monitoring is also important and sometimes prompts more frequent testing. Tuberous sclerosis primarily affects the brain, skin, eyes, kidneys, heart and bones. Infantile spasms had the highest rate of onset between 3 and 9 months, focal seizures had a relatively constant rate of onset up to 21 months, and other seizure types had an onset up to 26 months. Tuberous sclerosis (TS) is an autosomal dominant disorder. Usefulness of diagnostic criteria of tuberous sclerosis complex in pediatric patients. Thirty-six infants (28%) had >1 initial presenting feature. Both infantile spasms and focal seizures were seen in 36% and were more likely to co-occur than to occur alone in an individual (P = .02). It usually affects the central nervous system and can result in a combination of symptoms, including seizures, developmental delay, and behavioral problems. These characteristics add to the complexity of transition to adulthood. Up to 80% of patients with tuberous sclerosis complex will have at least 1 angiomyolipoma in their lifetime. An LC model using 3 classes best fit the data by using both information criteria and a test of log-likelihood functions (Supplemental Table 6). Advances in the treatment of tuberous sclerosis complex. Overwater IE, Bindels-de Heus K, Rietman AB, et al. A classical picture of Tuberous sclerosis is mental retardation, epilepsy and adenoma sebaceum. A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. All patients with only 1 major criterion had no minor criteria present and were diagnosed with definite TSC on the basis of genetic testing. Copy number variants and infantile spasms: evidence for abnormalities in ventral forebrain development and pathways of synaptic function. Wake Forest Baptist Medical Center Tuberous Sclerosis Clinic Director: Mary T. Silvia, MD Co-Director: Roy E. Strowd,III, MD Administrative Coordinator: Mary Jo Shirley Age Range Seen: Children and Adults. Given the morbidity and mortality when such a lesion is left undiagnosed, successive follow-up imaging in pediatric patients has been recommended. From the Tuberous Sclerosis Alliance were Roberds, S8 and Nakagawa, JA8. From the Data Coordinating Center was Cutter, G7. Tuberous sclerosis complex (TSC) is a rare disease caused by changes (also called “mutations”) in certain genes that control important proteins in the body, hamartin and tuberin. Dominant means that only 1 copy of the gene is needed to have the condition. Early findings of TSC in infants are often subtle and asymptomatic and may be missed if a child is not completely evaluated, leading to delayed diagnosis.16. CONCLUSIONS: Infants with TSC can often be identified early, before the onset of neurologic sequelae, enabling earlier diagnosis, surveillance, and possibly disease-modifying treatment.

TSC is a neurocutaneous genetic disease with an incidence of ∼1 in 6000 live births.4 It presents with a wide range of manifestations caused by localized cellular overgrowth, leading to benign tumors (hamartomas) in multiple organs. All neuroimaging was read as normal in 4%, whereas 3% had initial neuroimaging that was read as normal with subsequent neuroimaging showing a tuber or cortical dysplasia. Tuberous sclerosis is a genetic multisystem disorder characterised by widespread hamartomas in several organs, including the brain, heart, skin, eyes, kidney, lung, and liver. Patients usually have multisystem involvement and thus present to different medical specialties with varied complaints while the true nature of the disease and the hidden manifestations may remain unattended. For participants who did not have neuroimaging findings reported in the study database, sites provided anonymized reports from any MRI neuroimaging performed at the study site. Tuberous sclerosis complex is a rare genetic disease that causes benign tumors to grow in the brain and other parts of the body, such as the eyes, heart, kidneys, lungs, and skin. Tuberous Sclerosis. The diverse and varied presentations and progression can be Clinical and genotype studies of cardiac tumors in 154 patients with tuberous sclerosis complex. The study protocols were approved by the internal review boards at each site with direction from the leading regulatory core at Cincinnati Children’s Hospital Medical Center. Discovery of the disease‐causing genes, TSC1 and TSC2, has led to the unraveling of the molecular and cellular underpinnings of the disorder, and the discovery that mTOR inhibitors effectively stabilize and shrink many tuberous sclerosis complex‐associated tumors. Reported P values are for χ2 tests of independence except when noted. Every infant in this cohort had either hypomelanotic macules, cardiac rhabdomyomas, or both. Given the morbidity and mortality when such a lesion is left undiagnosed, successive follow-up imaging in pediatric patients has been recommended. The mean postnatal age of initial feature onset was 48 days (SD 72 days). By including adults and children in one comprehensive clinic, our specialists are able to provide continuity of care as patients born with tuberous sclerosis transition into adulthood. Profile of everolimus in the treatment of tuberous sclerosis complex: an evidence-based review of its place in therapy. Population studies estimate prevalence between 1 in 6000–9000 in the USA to 1 in 38 000 elsewhere. The most common initial presenting features were cardiac rhabdomyomas (59%) and hypomelanotic macules (39%), and 85% of patients presented with either or both. Renal cysts were the only minor feature prevalent enough to be included in analysis, but they were not a significant class indicator. Mutational analysis of TSC1 and TSC2 in Korean patients with tuberous sclerosis complex. 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. Two infants (2%) were diagnosed with definite TSC by genetic diagnostic criteria.14. Purpose: Tuberous sclerosis complex is a genetic disorder characterized by the growth of hamartomas in multiple organs. TSC can be challenging to diagnose in infants because they often do not show many clinical signs early in life. Epilepsy incidence in this cohort was 49% by 6 months, 73% by 12 months, and 80% by 24 months. For participants who did not have ophthalmologic findings reported, sites provided dates and findings from documented clinical ophthalmologic examinations; ophthalmologic examination results were reported for 87 subjects. Background: Tuberous sclerosis complex (TSC) is a rare genetic disease which leads to formation of benign tumors in the brain and other organs of the body. Topical sirolimus may be helpful for facial angiofibromas (1). Safety of everolimus in patients younger than 3 years of age: results from EXIST-1, a randomized, controlled clinical trial. Tuberous sclerosis complex is a dominantly inherited genetic disorder in which tumors (usually hamartomas) develop in multiple organs. Could targeted treatment safely and effectively modify the course and prognosis of the disease? This means: Girls and boys have an equal risk of having the condition. Any future updates to these recommendations will also be posted on this page. Studies using these drugs for these and other complications of TSC are ongoing. Darling T: Topical sirolimus to treat tuberous sclerosis complex (TSC). The onset dates of some features were based on parental report and thus were susceptible to recall bias, inaccurate reporting, or were unknown. Infants from urban areas closer to the 5 TSC center study sites were probably overrepresented in this cohort and more likely to come to medical attention early. SEGAs occurred in 6% of participants. We do not capture any email address. Vertex size is proportional to the prevalence of organ system involvement in a class. Tuberous sclerosis complex 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. Tuberous sclerosis complex (TSC) occurs in 1 in 6,000 individuals. Tuberous sclerosis complex is a genetic disorder characterized by hamartomatous lesions in multiple organs, frequently involving the kidney. Others included Scherrer, B1 and Leuchter, A4. What is tuberous sclerosis complex? The high prevalence of cardiac rhabdomyomas in this cohort when compared with other large population-based studies9,18 is likely due to the regression of these tumors in older individuals and is comparable to the youngest patients in previous studies in which researchers examined TSC manifestations in pediatric populations.36,37 Minor TSC features other than renal cysts were infrequently found, and minor features did not contribute to the diagnosis of any infant. Age of onset or recognition of the most prevalent major TSC features plus seizures and renal cysts is shown in Fig 2. Overall seizure prevalence was higher in girls (84%) than boys (69%) (P = .05), although the difference was not statistically significant for each individual seizure type. The skin, heart, eyes, kidneys, and lungs may also be affected in varying degrees.5 Dysfunction of hamartin and tuberin, the protein products of the TSC1 and TSC2 genes, results in upregulation of the mechanistic (formerly mammalian) target of the rapamycin (mTOR) pathway and produces dysregulated cellular growth.6,7 mTOR inhibitors are used to treat SEGAs, renal angiomyolipomas, facial angiofibromas, and pulmonary lymphangioleiomyomatosis.2 Most patients with TSC also develop neurologic and neuropsychiatric disorders: up to 90% develop epilepsy,8,9 and up to 50% develop autism.10 Studies have shown that mTOR inhibitors may have disease-modifying effects in TSC-associated neurologic and neuropsychiatric disorders.11 Treating infants with TSC and epilepsy earlier with antiepileptic medications or surgery may result in better neurologic outcomes, reinforcing the importance of early diagnosis.12,13. Presentation and diagnosis of tuberous sclerosis complex in infants.Pediatrics If a date of onset was unknown, the date of the study visit when the feature was first noted was used as a conservative replacement when needed for calculations. Clinical presentation and diagnosis of tuberous sclerosis complex in infancy. Autosomal means that both boys and girls are affected. Tuberous sclerosis complex can be associated with a wide range of signs and symptoms, most of which are related to the tumors caused by the disease. National Institutes of Health project scientists were Mamounas, L9 and Kau, A10. Dallas. Nonsense variants were more common in TSC1 (53%) than TSC2 (24%) (P = .02), and missense variants and small and large deletions were only seen in TSC2. Pediatr Neurol 49(4):243–254, 2013. doi: 10.1016/j.pediatrneurol.2013.08.001. The rate of onset for a first seizure of any type was greatest in the first year of life but began to level off at ∼9 months. Report of the Guideline Development Subcommittee of the American Academy of Neurology and the Practice Committee of the Child Neurology Society. The 30% inherited and 70% de novo rate in infants with both parents tested is consistent with previously reported rates in TSC.38–42 Future studies of more detailed genotype-phenotype relationships in infants with TSC are needed, and data from this study will contribute to those studies. * A definite diagnosis of TSC requires either of the following: A possible diagnosis of TSC requires the following: † Includes central nervous system tubers and cerebral white matter radial migration lines. Informed consent was obtained from the parents or legal guardians of all participants. BACKGROUND: Tuberous sclerosis complex (TSC) is a neuro-cutaneous disease characterized by hamartoma formation in various organs particularly the skin, brain, eye, kidney, heart and lungs. (2017). Davis, PE Filip-Dhima, R Sideridis, G Peters, JM Au, KS Northrup, H et al. The International Tuberous Sclerosis Complex Consensus Conference of 2012 defined major and minor criteria for making a definite or possible diagnosis of TSC (1; see table International Tuberous Sclerosis Complex (TSC) Consensus Conference Criteria for the Diagnosis of TSC). Pediatric Tuberous Sclerosis (TSC) Tuberous sclerosis (TSC) is a genetic condition that causes benign (noncancerous) tumors to grow in the brain and on other parts of the body, such as the skin, brain and kidneys. Tuberous sclerosis complex is a genetic disorder characterized by hamartomatous lesions in multiple organs, frequently involving the kidney.

NewYork-Presbyterian/Columbia University Irving Medical Center is home to a dedicated team of pediatric and adult healthcare professionals from multiple disciplines who collaborate to care for people with tuberous sclerosis complex (TSC), a genetic disorder which can affect multiple organs. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. A small percentage of tuberous sclerosis patients will develop a subependymal giant-cell astrocytoma. 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. Prognosis depends on symptom severity. Tuberous sclerosis was classically described as presenting in childhood with a triad (Vogt triad) of: 1. seizures: absent in one-quarter of individuals 2. intellectual disability: up to half have normal intelligence 3. adenoma sebaceum: only present in about three-quarters of patients1 The full triad is only seen in a minority of patients (~30%). 1. Merck and Co., Inc., Kenilworth, NJ, USA (known as MSD outside the US and Canada) is a global healthcare leader working to help the world be well. A café-au-lait spot is a hyperpigmented (brownish or coffee-colored) macule. The study was conducted in accordance with Good Clinical Practice guidelines. By the age of 5 - 10 yrs, it is possible to predict the extent of the disease and problems that can occur later. Tuberous sclerosis is an autosomal dominant genetic condition that is caused by a change (pathogenic variant) in either the TSC1 or TSC2 gene. Co-investigators were Warfield, S1; Peters, J1; Scherrer, B1; and Goyal, M3. Adjunctive everolimus therapy for treatment-resistant focal-onset seizures associated with tuberous sclerosis (EXIST-3): a phase 3, randomised, double-blind, placebo-controlled study. 2013;49:243-254. The proportion of infants who had involvement of each organ system and the proportion who had involvement of each pair of organ systems are depicted graphically for all subjects and for each class separately in Fig 5. The hamartin–tuberin complex inhibits the mammalian-target-of-rapamycin pathway, which controls cell growth and proliferation. At Boston Children’s Hospital, the Multidisciplinary Tuberous Sclerosis Program is a team of pediatric specialists who are dedicated to providing coordinated care for children with TSC. The trusted provider of medical information since 1899, Neonatal Herpes Simplex Virus (HSV) Infection. It can also cause intellectual disability, developmental delays, seizures, and learning disabilities. The date of onset for each TSC feature was used to calculate the days between date of birth and onset or to determine if reported onset was prenatal. One limitation of this study is that genetic testing was limited to TSC1 and TSC2 sequence and deletion or duplication testing. Patients usually have multisystem involvement and thus present to different medical specialties with varied complaints while the true nature of the disease and the hidden manifestations may remain unattended. However, all 5 had hypomelanotic macules reported as present within the first few months of life, so early skin findings may have prompted imaging but were reported by parents as occurring later. These proteins control how cells grow and tell them when to stop growing. Kidney disease may cause hypertension. Subject demographics are summarized in Table 2. Epilepsy in newborns with tuberous sclerosis complex. See tuberous sclerosis diagnostic criteria 2. Cardiac myomas may develop prenatally, sometimes causing heart failure in neonates. Tuberous sclerosis associated neuropsychiatric disorders (TAND) and the TAND checklist. BACKGROUND: Tuberous sclerosis complex (TSC) is a neuro-cutaneous disease characterized by hamartoma formation in various organs particularly the skin, brain, eye, kidney, heart and lungs. The UT Tuberous Sclerosis Center of Excellence encompasses comprehensive care and research for pediatric and adult patients with Tuberous sclerosis complex. The TS Alliance encourages sharing these links, or a link to www.tsalliance.org/consensuswith healthcare providers. When skin lesions are absent, as in 20% to 30% of all cases, clinical diagnosis becomes difficult. Of the 108 individuals with tubers or cortical dysplasias seen on neuroimaging, 80% developed seizures. Seizure onset prevalence by age and seizure type (infantile spasms, focal seizures, or other) is shown in Fig 4. We also thank the Tuberous Sclerosis Alliance for its continued support of TSC research. When skin lesions are absent, as in 20% to 30% of all cases, clinical diagnosis becomes difficult. How early can we identify patients with TSC? Northrup H, D Krueger D, and on behalf of the International Tuberous Sclerosis Complex Consensus Group: Tuberous sclerosis complex diagnostic criteria update: Recommendations of the 2012 International Tuberous Sclerosis Complex Consensus Conference. A definite diagnosis of TSC by these criteria requires either of the following: The identification of either a TSC1 or TSC2 pathogenic mutation in DNA from normal tissue, Two major features or 1 major feature with ≥ 2 minor features. The natural history of epilepsy in tuberous sclerosis complex. The University of Chicago Medicine is home to a unique tuberous sclerosis program, where pediatric neurologists and neurosurgeons diagnose and manage this condition in patients of all ages. JAMA Dermatol 154(7):761–762, 2018. doi: 10.1001/jamadermatol.2018.0465. Recommendations From the International Tuberous Sclerosis Complex Consensus Conference 2012, Pediatric Neurology (December 2013) *Leclezio L et al. TUBEROUS SCLEROSIS is a rare condition of infancy and childhood with a diagnostic triad of retarded mental development, convulsions, and sebaceous adenomata of the face. Sometimes tubers undergo malignant degeneration into gliomas, particularly subependymal giant cell astrocytomas (SEGAs). Data from each study site were entered into a Web-based, distributed data management system meeting Health Insurance Portability and Accountability Act privacy regulations. E-mail: Copyright © 2017 by the American Academy of Pediatrics. This prospective study of infants with TSC recruited from 5 major medical centers across the United States demonstrates that we are capable of making an early diagnosis of TSC in many infants. Infantile spasms had the highest rate of onset between 3 and 9 months, whereas focal seizures had a more constant rate of onset up to 21 months, and other seizure types had a rate of up to 26 months. Recommendations from the International Tuberous Sclerosis Complex Consensus Conference 2012. Neuroimaging findings were seen at presentation in 16% of participants; an additional 37% had neuroimaging findings at diagnosis. Wake Forest Baptist Medical Center Tuberous Sclerosis Clinic Director: Mary T. Silvia, MD Co-Director: Roy E. Strowd,III, MD Administrative Coordinator: Mary Jo Shirley Age Range Seen: Children and Adults. TSC may be suspected when fetal ultrasonography detects cardiac myomas or when infantile spasms occur. Physical examination is done to check for typical skin lesions. In this article, we analyze the timing and pattern of clinical presenting and diagnostic features in infants with TSC to better understand how TSC presents in this unique population and how it can be diagnosed and treated earlier. Initially pale, ash leaf–shaped macules, which develop during infancy or early childhood, Angiofibromas of the face (adenoma sebaceum), which develop during later childhood, Congenital shagreen patches (raised lesions resembling an orange peel), usually on the back, Subungual fibromas, which can develop any time during childhood or early adulthood. Of 87 infants with documented ophthalmologic examinations or findings, 43% had retinal hamartomas, and 6% had retinal achromic patches. Epilepsy is the most common neurologic manifestation of TSC, affecting approximately 85% of patients, with onset often during infancy ystems, most frequently in … Intellectual abilities in tuberous sclerosis complex: risk factors and correlates from the Tuberous Sclerosis 2000 Study. Clinical and genotype studies of cardiac tumors in 154 patients with tuberous sclerosis complex. We examined the relationship of each TSC feature and type of variant to the affected TSC gene. International Tuberous Sclerosis Complex Consensus Group. Thirty-five percent of infants presented prenatally, 41% presented at birth or within the first month of life, and 74% met criteria for TSC diagnosis at or within 30 days of presentation. Cardiac rhabdomyomas were seen on prenatal imaging in 35% of patients, and 3% met diagnostic criteria for TSC prenatally with brain involvement also seen on imaging (Fig 1). There are several ways in which this disease is transmitted to the neonate. Of 12 infants with rhabdomyomas recorded postnatally as the initial presenting feature, 4 had a heart murmur, 3 had another clinical indication for an echocardiogram (concern for aortic coarctation, abnormal heart sounds, and perinatal distress), and 2 had a positive family history. These reports were reviewed for any findings of cortical tubers or dysplasia, SENs, or SEGAs. Rare autosomal dominant, multi-systemic disease causing benign tumors to grow in brain, kidneys, heart, eyes, lungs, and … Development of headaches, loss of skills, or new kinds of seizures may be caused by malignant degeneration or growth of CNS tubers and are indications for neuroimaging. INTRODUCTION. Tuberous sclerosis complex affects approximately 40,000 people in the United States. Introduction: Tuberous sclerosis complex (TSC) is a multisystemic genetic disease with high clinical variability and age-related manifestations. The areas are 1 to 3 cm in length and may be more easily seen under ultraviolet light (Wood light). 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 affected genes are TSC1 and TSC2, encoding hamartin and tuberin respectively. At Boston Children’s Hospital, the Multidisciplinary Tuberous Sclerosis Program is a team of pediatric specialists who are dedicated to providing coordinated care for children with TSC. The mTOR signaling cascade: paving new roads to cure neurological disease. Data were collected in a standardized, rigorous manner, and study sites were queried for clarifications and to provide missing data. Pediatrics. Funded by the National Institutes of Health (NIH). 2006 Oct;118(4):e1146-51. Note the different patterns and prevalences of organ system involvement and co-occurrence in each class. The understanding and treatment of tuberous sclerosis complex (TSC) have advanced significantly in the last 2 decades.1 After the identification and sequencing of the genes responsible for TSC in the 1990s, the biochemical pathway at the root of the disorder was mapped, leading to effective treatments aimed at the underlying disease mechanism.2,3 However, much remains to be discovered. Clinic Frequency: Pediatrics–2-3 Thursdays a month, subject to … Objectives: Tuberous sclerosis complex (TSC) is a neurocutaneous genetic disorder with a high prevalence of epilepsy and neurodevelopmental disorders. However, neuroimaging in TSC may initially appear normal, with tubers or cortical dysplasias only becoming apparent later with progressive myelination, as occurred in 3 individuals. Infantile spasms syndrome, West syndrome and related phenotypes: what we know in 2013. Other limitations generally reflected the study design. Tuberous sclerosis drug clears Phase III trial | Pediatric Insights December 2012 An important Phase III clinical trial confirms that the anti-rejection drug everolimus can dramatically reduce brain tumor growth in patients with tuberous sclerosis complex (TSC). If either parent has the disorder, children have a 50% risk of having it. The following papers preceded by an asterisk are available free of charge with open access to anyone in the world. TUBEROUS SCLEROSIS is a rare condition of infancy and childhood with a diagnostic triad of retarded mental development, convulsions, and sebaceous adenomata of the face. Tuberous sclerosis complex is characterized by the occurrence of benign hamartomas in multiple organs. Tuberous sclerosis complex affects approximately 40,000 people in the United States. Thus, minor criteria did not contribute to the diagnosis of TSC in any infant. This causes growths called tubers to grow in the brain and retina of the eye. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. Dr Sahin has received research funding from F. Hoffman-La Roche AG, Novartis, Pfizer, and LAM Therapeutics; has served on the scientific advisory board of Sage Therapeutics Inc. and PTEN Research Foundation; and serves on the professional advisory board of the Tuberous Sclerosis Alliance. It usually affects the central nervous system and can result in a combination of symptoms, including seizures, developmental delay, and behavioral problems. Neuroimaging without tubers or cortical dysplasias had a high negative predictive value for the development of epilepsy by age 36 months. The enrollment goal was 150 infants; infants were eligible if they met genetic or clinical diagnostic criteria for TSC on the basis of current recommendations for diagnostic evaluation.14 Data collected at study visits included medical and seizure histories, physical and neurologic examinations, and developmental assessments. 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. This means: Girls and boys have an equal risk of having the condition. Population studies estimate prevalence between 1 in 6000–9000 in the USA to 1 in 38 000 elsewhere. Central nervous system (CNS) tubers interrupt neural circuits, causing developmental delay and cognitive impairment and may cause seizures, including infantile spasms. The antiepileptic medication vigabatrin is particularly effective in treating infantile spasms in TSC2,24 and has mTOR-inhibiting effects.25 Vigabatrin is currently in clinical trials to determine its efficacy at preventing epilepsy in patients with TSC (Preventing Epilepsy Using Vigabatrin In Infants in the United States [NCT02849457] and Long-term, Prospective Study Evaluating Clinical and Molecular Biomarkers of Epileptogenesis in a Genetic Model of Epilepsy - Tuberous Sclerosis Complex in the European Union [NCT02098759]).
