Brief Summary

The TSC Biosample Repository collects and stores samples of blood, DNA, and tissues that scientists can request to use in their research. The samples we collect are all linked to clinical data in the TSC Natural History Database. 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. This data may be collected retrospectively or prospectively.

Outcome Measures

Primary Outcomes (1)

  • Natural History data and biosamples including blood, tissue, or other types of biological samples from individuals with TSC

    The purposes of this project are to: * Collect biosamples such as blood, tissue, fluid, or other types of bodily samples from people with TSC. * Collect information about people with TSC over their lifetime.

    Average 15 years

Interventions

PhlebotomyPROCEDURE

Participants may elect to submit a blood sample to the Biosample Repository.

Participants may elect to submit a buccal swab sample to the Biosample Repository.

Biosamples may be processed and analyzed for genetic variants using whole genome sequencing (WGS) or other sequencing methods. Participants whose samples are processed in this manner may be contacted and provided the option to receive TSC1 or TSC2 genetic variant results by opting in using Consent to Return of Genetic Results Form. Participants will be offered a one-time genetic counseling session to review their results, free of charge. CLIA-certified, TSC1 or TSC2 genetic variant results will be returned to participants who opt in to receive such results. Additionally, negative results and results not able to be clinically certified will also be offered to participants with a one-time genetic counseling session to review their results, free of charge using the Return of Genetic Research Results Template Letter. CSS will be responsible for informing clinic participants that their samples have been sequenced and offer to connect participant to the TSC Alliance for further information.

Participants may elect to submit a tissue sample to the Biosample Repository following a medical procedure.

Study Population

An individual must have a diagnosis of tuberous sclerosis complex, based on the current clinical and genetic diagnostic criteria. The individual may enroll if they have a diagnosis of sporadic LAM. All persons with tuberous sclerosis complex are eligible to participate, such as individuals with limited decisional capacity.

You may qualify if:

  • Diagnosis of tuberous sclerosis complex or lymphangioleiomyomatosis (sporadic LAM).

Retention: SAMPLES WITH DNA

Biological materials will be collected at different timepoints in conjunction with procedures that are done for clinical reasons or when consent is given to collect the sample expressly for this research study. Historical cord blood, dried blood spot or placental tissue samples may be collected. Postmortem organ tissue may be collected with consent from the parent/legal guardian of the deceased person with TSC who was enrolled in this protocol or from whom medical records are available to enter relevant clinical data in the NHD. Blood spots may be collected using at-home commercial devices shipped to participants or at CSS using available resources. Blood spots may be created when blood samples arrive at VAI. Biosamples may be processed and analyzed for genetic variants using whole genome sequencing (WGS) or other sequencing methods.
