However, couples with a personal or family history of the disease can receive genetic counseling to assess the risks of having children with the condition [\[1\]](). Tuberous Sclerosis Complex is a genetic disorder that affects multiple systems in the body, including the skin, brain, kidneys, heart, and lungs [\[1\]](). The disease results from changes in one of two genes: TSC1 or TSC2. In two-thirds of cases, these genetic changes occur spontaneously (de novo mutations) without a family history of the disease [\[1\]](). ## Understanding Genetic Causes and Inheritance Tuberous Sclerosis Complex is caused by mutations in the TSC1 or TSC2 genes. In cases where one parent has Tuberous Sclerosis Complex, each child has a 50% chance of inheriting the disease [\[1\]](). This pattern of inheritance makes genetic counseling an important tool for affected families. However, the majority of cases (two-thirds of cases) are caused by new genetic mutations, meaning the disease appears in the child without being present in the family history, and these cases cannot be predicted or prevented [\[1\]](). ## The Role of Genetic Counseling Genetic counseling is a crucial step for couples with a personal or family history of Tuberous Sclerosis Complex who wish to have children. A genetic counselor can provide information on inheritance patterns, the risk of disease transmission, and available diagnostic options [\[1\]](). This helps couples make informed decisions regarding family planning. ## Prenatal Diagnosis In families with a known genetic mutation or a history of Tuberous Sclerosis Complex, prenatal diagnosis is available [\[1\]](). This may include genetic testing to determine if the fetus has inherited the disease-causing mutation. However, it is important to note that Tuberous Sclerosis Complex often appears as a new mutation in the DNA, and these cases cannot be prevented through prenatal diagnosis unless the mutation is already known in the family [\[1\]](). ## Managing the Disease After Diagnosis Although there is no cure for Tuberous Sclerosis Complex, treatment focuses on managing the symptoms and complications that may arise [\[2\]](). This includes medications to control seizures, laser therapy for skin lesions, and medications that target tumors in the brain and kidneys [\[1\]](). Regular follow-up with specialized physicians is important to manage the disease effectively.
