About this study

Official title: Human Biospecimen Procurement and Analysis to Support Translational Research to Identify Genetic Etiology and Disease Mechanism(s) in Rare Genetic Vascular/Cardiovascular Diseases

Background:

Studies show that rare genetic variants might lead to diseases. Researchers want to collect blood and tissue samples so they can study them and better understand diseases.

Objective:

To collect blood and tissue samples for studies to identify underlying causes of disease.

Eligibility:

People of all ages

Design:

Participants will have blood and/or tissue samples collected.

Samples can be collected at the NIH Clinical Center. Participants doctors can collect the samples and send them to NIH. NIH staff can collect samples off site.

For blood samples, blood is taken from an arm vein using a needle.

Tissue collection may involve:

Buccal smear: Cells are collected by scraping the inside of the cheek with a cotton swab.

Saliva collection: Participants spit into a cup.

Skin biopsy: A special needle takes a very small skin sample.

Surgical waste tissue: If participants have surgery, NIH may receive samples of tissue that

would routinely be removed.

Umbilical cord or cord blood collection: If a participant has a baby, NIH may receive a

small piece of the umbilical cord or blood from the cord once the baby is delivered.

Read the detailed description

The diversity of human research programs at the National Institutes of Health (NIH) provides a unique opportunity to study different patient populations with monogenetic and undiagnosed diseases with vascular implications. Patient populations with mutations in almost every major signaling pathway related to cardiovascular diseases are actively investigated at the NIH Clinical Center. The purpose of this protocol is to obtain and analyze human biospecimens from affected and unaffected cohorts (as reference biospecimens) to identify genetic etiology and/or underlying disease mechanism(s) in rare genetic vascular/cardiovascular conditions. The collections will consist of biospecimens obtained from participants consented under this protocol and will also provide for the continued storage and analysis of biospecimens previously obtained from NIH Institutional Review Board (IRB)-approved protocols, or from NIH protocols nearing completion. The biospecimens collected under this protocol will include blood (plasma, serum, peripheral blood mononuclear cells (PBMCs)), saliva, buccal mucosa, urine, and skin biopsies. Additional biospecimens collected under other protocols may also be transferred to this protocol, including, tissue and fluid aspirates (cerebrospinal fluid, ascites, etc.), bone marrow, urine, saliva, skin biopsies, surgical tissue waste, malignant and non-malignant tissue samples, and/or other direct derivatives from human tissues (i.e. DNA, RNA, and induced pluripotent stems cells). Post-delivery umbilical cord core blood and cord tissue waste will be collected at the time of delivery under this protocol and/or shared if obtained under other protocols. Biospecimens may also be obtained as shared samples of clinically indicated procedures done inside or outside NIH, provided the subject consents to this protocol.

The primary objective of this protocol is to create a robust resource to support basic and translational research by providing a mechanism for collecting, tracking, storing, dispensing, analyzing, and disposing of laboratory research samples from affected and unaffected cohorts. This research will advance high-quality research in the areas of genetics and personalized medicine.

As this is not a treatment protocol, there is no primary endpoint. Research studies will include, but not be limited to, genomic studies, primary cell isolation and cell culture studies for molecular and biochemical analysis, immunohistological analysis, generation of patient-specific in vitro disease models (i.e. IPSCs), etc. As science is a continuously evolving field, technological advances in research methods will be incorporated into research studies accordingly.

Questions about this trial

What is this clinical trial studying?

An observational study of Undiagnosed Diseases and Cardiovascular Disease, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Ruth C Brower, R.N. ((301) 443-6036, ruth.brower@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To procure human biospecimens from affected and unaffected cohorts for on-going and future basic and translational research studies to identify underlying disease mechanism(s) (time frame: ongoing). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2026.
