    Observational What is this?

    Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

Background: Autosomal recessive bestrophinopathy (ARB) is one of 5 blinding eye diseases caused by mutations in the gene BEST1. These diseases, collectively termed "bestrophinopathies" include ARB, Best vitelliform macular dystrophy (BVMD), adult-onset vitelliform dystrophy (AVMD), autosomal dominant vitreoretinalchoroidopathy (ADVIRC) and retinitis pigmentosa (RP) .

Objective: To collect DNA/RNA and skin samples from individuals with ARB or other diseases due to mutations in the gene BEST1. These models will be used to identify and test therapeutic approaches to treating these diseases.

Design: Study involves a one time donation of a skin punch biopsy and whole blood. Once the skin biopsy is obtained, skin fibroblasts will be isolated, which will be reprogrammed into iPSCs. RPE cells will be derived from the iPSCs

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • Patient must have been diagnosed on the basis of genotyping with a bestrophinopathy.
  • Patient must be willing to provide a skin biopsy from which we will generate ipSCs. For pediatric patients, parents must be willing to donate skin biopsies as well.

Exclusion Criteria:

  • Children under the age of 5 will be excluded.
  • Patients exhibiting secondary ophthalmic disorders that are not typically associated with the bestrophinopathies may be excluded.
  • Pregnant women will be excluded from this study.
