National Tuberous Sclerosis Awareness Month is observed throughout May. The month is set aside to increase awareness about tuberous sclerosis, a rare genetic disorder. The month recognizes the suffering of people who are living with this disorder. It also aims to counteract the social exclusion and stigmatization that they face. During this month, organizations and individuals have an opportunity to extend their support to people suffering from tuberous sclerosis through funding research towards easing symptoms of the disease and empowering healthcare providers, educators, and families of people living with the disorder, as well as other caregivers.

History of National Tuberous Sclerosis Awareness Month

Tuberous sclerosis, also known as Tuberous Sclerosis Complex (T.S.C.) or Bourneville-Pringle disease, is a rare genetic disease. It belongs to the group of so-called neurocutaneous disorders.

Tuberous sclerosis happens due to mutation in the TSC1 or TSC2 genes. These genes involved in cell growth lead to excessive growth and multiple tumors in the body.

The Tuberous Sclerosis Complex are non-cancerous ‘benign’ tumors that grow in different parts of the body. The organs most often affected by these tumors are the brain, skin, kidneys, heart, eyes, and lungs. Tuberous sclerosis is present from birth, although it may not cause problems immediately. One in 6,000 people globally is born with such a mutation.

Only one parent needs to have the faulty gene to pass it on to their child. A parent who has one of the faulty genes has a 50% chance of passing it on to each child they have. The parent carrying the faulty gene will also have the disease, although it may be so mild they do not realize it.

T.S.C. can have many different manifestations. Treatment of tuberous sclerosis complex is focused on managing symptoms and is symptom-specific. For example, T.S.C. patients with epilepsy are treated with drugs and approaches commonly used to treat childhood epilepsy.

Another example is the drug Rapamycin and its derivatives (such as everolimus), also known as ‘mTOR inhibitors,’ being sometimes used to treat tumors and/or epilepsy caused by tuberous sclerosis complex. Thankfully, advances in science and medicine, better treatment, proper care, and public awareness of the serious problems patients face all contribute to a significant improvement in their lives.

Tuberous sclerosis is often a huge trauma not only for patients due to social reactions but also for their families. National Tuberous Sclerosis Awareness Month is a time to stand in solidarity with people with T.S.C and their caregivers.
