  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Participants with inherited eye diseases or their unaffected relatives.

Who may be able to join

  • To participate in this protocol:
  • 1a. The participant must present with characteristics that meet minimal clinical criteria established by eyeGENE, as determined by the referring clinician.

About this study

Official title: National Ophthalmic Genotyping and Phenotyping Network Stage 1 - Creation of DNA Repository for Inherited Ophthalmic Diseases

The National Ophthalmic Disease Genotyping and Phenotyping Network (eyeGENE(R)) is a genomic medicine initiative created by the National Eye Institute (NEI), part of the National Institutes of Health (NIH), in partnership with clinics and laboratories across the vision research community. The core mission of eyeGENE(R) is to facilitate research into the causes and mechanisms of rare inherited eye diseases and accelerate pathways to treatments. This study collects DNA samples from patients with inherited eye diseases to facilitate research to identify genetic factors responsible for these conditions. Nearly 500 genes that contribute to inherited eye diseases have been identified. As a result, gene-based therapies are being pursued to treat eye genetic diseases that were once considered untreatable.

Physicians in collaborating institutions will recruit patients to participate in the study. Patients will provide a blood sample and undergo a standard eye examination. The blood sample and clinical information will then be sent to the NEI for testing, processing and storing in the biorepository. Patients are given the option to receive results back and/or to be re-contacted in the event of future clinical studies. Information supplied to the testing laboratories includes a unique identification number, the patient gender, and the patient date of birth. The stored samples are available to researchers along with information about the patient's disease, but without patient identifiers.

Read the detailed description

Molecular genetics has the potential to revolutionize the diagnosis and treatment of inherited eye diseases. Progress in research on inherited eye disease would be augmented by the availability of patient DNA coupled to robust, anonymous phenotypic information. The National Ophthalmic Genotyping and Phenotyping Network (eyeGENE(R)) has been created to answer this need. By creating a national DNA and blood repository for inherited eye disease. These samples have been gathered from clinical centers around the nation and will be coupled to anonymous, phenotypic descriptors. If requested, a portion of the sample submitted by a clinician can be used for appropriate, CLIA-certified molecular diagnostics that can be used in patient care. Once a sufficient repository is created, researchers will be able to request aliquots for their laboratory experiments. Participants will be provided the option to be re-contacted if an approved clinical study for which they might qualify is offered. Researchers can request aliquots for their laboratory experiments or ask the eyeGENE(R) Coordinating Center to re-contact participants to inform them about the possibility to participate in a clinical study.

Questions about this trial

What is this clinical trial studying?

An observational study of Retinitis Pigmentosa and Inherited Ophthalmic Diseases, run by National Eye Institute (NEI) 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 5 inclusion and 5 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: finished, as of the sponsor's last update on 8 Dec 2025. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Obtain samples for the creation of eyeGENE network (time frame: 34 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00378742, which also lists 4 linked publications.

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 8 Dec 2025.
