Natural History Database

Implemented in 2006, the TSC Natural History Database captures clinical data to document the impact of the disease on a person’s health over his or her lifetime. More than 2,000 people with TSC are enrolled in the project among 18 U.S.-based clinical sites. The TS Alliance provides funding to participating clinics to perform data entry, monitors the integrity of the database, and makes data available to investigators to answer specific research questions and identify potential participants for clinical trials and studies.

Since 2010, researchers have published seven articles in well-regarded, peer-reviewed biomedical journals using data from the TSC Natural History Database. This published research has contributed to our understanding of TSC in a number of relevant fields, including neurology, psychiatry, and ophthalmology. Several papers have found correlations between gene mutations and specific TSC symptoms, as well as correlations between different kinds of symptoms. This type of work is helping us understand why and how different individuals with TSC experience the disease differently.

Please see the TS Alliance Mendeley group for more information on these papers, as well as other articles produced with the help of TS Alliance grants, data, and biosamples.
