  Purpose

Background:

- Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, and blood can be used for research. Researchers want to collect cells from people with Best disease, L-ORD, and AMD, and compare their cells with those of healthy volunteers.

Objectives:

- To collect hair, skin, and blood samples to study three eye diseases that affect the retina: Best disease, L-ORD, and AMD.

Eligibility:

  • Individuals at least 18 years of age who have Best disease, L-ORD, or AMD in at least one eye.
  • Healthy volunteers at least 18 years of age.

Design:

  • The study requires one visit to the National Eye Institute.
  • Participants will be screened with a medical and eye disease history. They will also have an eye exam.
  • Participants will provide a hair sample, a blood sample, and a skin biopsy. The hair will be collected from the back of the head, and the skin will be collected from the inside of the upper arm.

Criteria
  • INCLUSION CRITERIA:

To be eligible, participants must meet the following inclusion criteria:

  1. Participant has the ability to understand and sign an informed consent.
  2. Participant meets one of the following criteria:

    1. Participant has been diagnosed with Best disease, defined as the presence of lipofuscin-like deposits in the subretinal space and definitive mutations in the BEST1 gene.
    2. Participant has been diagnosed with L-ORD, defined as problems in dark adaptation and the loss of rod and cone function, subretinal deposits, RPE atrophy and hemorrhage, and long anterior zonules in the lens.
    3. Participant has been diagnosed with AMD, defined as the presence of:

    i. large drusen in both eyes along with pigmentary changes with or without advanced AMD (neovascular AMD), or

    ii. geographic atrophy in at least one eye.

    d. Participant has been diagnosed with LCA, defined as a presentation that is typical of the disease and mutations in a known LCA gene. Particular attention will be placed on patients with CRX, CEP290 and NPHP5 mutations, although other genotypes may be collected.

    e. Participant has been diagnosed with Joubert syndrome, defined as the presence of retinal dysfunction and/or degeneration and mutations in a known Joubert gene. Particular attention will be placed on patients with CEP290 or CC2D2A mutations, although other genotypes may be collected.

    f. Participant has been diagnosed with X-linked RP, defined as a presentation that is typical of the disease and mutations in a known X linked RP gene. Particular attention will placed on patients with RPGR or RP2 mutations, although other genotypes may be collected.

    g. Participant diagnosed with oculocutaneous albinism, of any molecular subtype, defined as classic clinical presentation

    h. Participant has been diagnosed with Stargardt's disease, defined as classic clinical presentation with at least one disease causing mutation in the ABCA4 gene.

    i. Participant has been diagnosed with Waardenburg syndrome, defined as classic clinical presentation and/or disease causing mutation in the MITF gene.

    j. Participant has a clinical presentation consistent with the papilorenal syndrome and has a confirmed mutation in the PAX2 gene.

    k. Participant has a clinical presetntation consistent with aniridia and has a confirmed mutation in the PAX6 gene.

    l. Participant has been diagnosed with coloboma, defined as a defect in the iris, neural retina/RPE/choroid and/or optic nerve consistent with a failure of optic fissure closure.

    m. Participant has been diagnosed with ESCS without the presence of macular edema, defined as a combination of 1) a constellation of symptoms including early onset nyctalopia, visual field defects, and possible central vision loss; 2) signs including vitreous degenerative changes and characteristic retinal exam findings; 3) diagnostic electroretinography pattern; and 4) family history of disease.

    n. Participant has been diagnosed with SCA7, as defined by CAG repeat expansion in the ATXN7 gene of greater than 18 repeats. Accrual will be biased towards those with repeat expansion lengths > 35, where clinical symptoms are most likely to manifest.

    o. Participant is free of eye diseases and could serve as an unaffected control. Participant s age (within five years), gender, and ethnicity must match an existing participant with one of the eye diseases under study. Control participants matched to AMD participants must not have drusen greater than 63 microns in size.

  3. Adult participant is able to provide a punch skin biopsy and 30 mL of peripheral venous blood OR child participant is able to provide a punch skin biopsy and the lesser of 5 mL/kg or 30 mL of peripheral venous blood. Sampling of ten occipital hairs may be pursued at the investigator s discretion. As a rule, samples will be collected on nonsedated/ anesthetized participants. Sedation/anesthesia will NOT be used solely for the purpose of sample collection. In rare instances where a minor requires sedation for another medically indicated procedure, samples may be collected at the time of sedation/anesthesia. Because young children may not be able to cooperate with sample collection, those unable to provide a skin biopsy and a blood sample may be excluded from the study, based on the judgment of the examining investigator.
  4. Participant meets one of the following criteria:

    1. Participant affected with LCA, Joubert syndrome, RP, OCA, Stargardt s disease, Waardenburg syndrome, coloboma, ESCS, SCA7 or eye disease due to MITF, PAX2, or PAX6 mutations is one year of age or older.
    2. Participant affected with Best disease, L-ORD, or AMD is 18 years of age or older.
    3. Unaffected participant is seven years of age or older and willing and able to provide assent.

EXCLUSION CRITERIA:

A participant is not eligible if any of the following exclusion criteria are present.

  1. Participant is unable to comply with study procedures.
  2. Participant has a systemic disease that, in the opinion of the investigator, compromises the ability to provide adequate samples.

Examples of co-existing diseases that would exclude a participant include a bleeding diathesis or a genetic susceptibility to infections, particularly cutaneous infections.

Additional Criteria for Clinical-Grade Cell Line Generation

The additional eligibility criteria must be met for participants donating samples for the generation of clinical-grade cell lines.

Inclusion Criteria

  1. Participant must be greater than 18 years of age, as of the date of enrollment. There is no upper age limit for donor enrollment.
  2. Participant is able to provide a punch skin biopsy and 100 ml of peripheral venous blood.
