Juvenile cataract in Hutterites.

M H Shokeir, R B Lowry

    American Journal of Medical Genetics
    |November 1, 1985
    PubMed
    Summary
    This summary is machine-generated.

    This study identifies isolated juvenile cataracts as a rare, recessive genetic trait in a Hutterite kindred. Affected individuals showed no other health issues, suggesting a specific genetic cause for their cataracts.

    Area of Science:

    • Ophthalmology
    • Medical Genetics

    Background:

    • Isolated juvenile or congenital cataract is a rare condition, often linked to systemic disorders or syndromes.
    • Genetic determination is possible, with autosomal dominant inheritance being more common than autosomal recessive transmission for isolated cases.

    Observation:

    • A study of four sibships within an extensive Hutterite kindred revealed nine individuals with juvenile or congenital cataracts.
    • These individuals, from Canada and the United States, were otherwise healthy, exhibiting normal growth, development, intellect, hearing, behavior, and neurological status.
    • No metabolic disorders or other ocular lesions were identified in the affected patients.

    Findings:

    • The Hutterite kindred presented a unique instance where isolated juvenile cataracts appeared to be inherited as a recessive trait.

  • This contrasts with the more commonly observed autosomal dominant inheritance pattern for isolated juvenile cataracts.

    • Implications:

    • This finding suggests a specific autosomal recessive gene is responsible for isolated juvenile cataracts in this Hutterite population.
    • Further research into this specific genetic locus could provide insights into cataractogenesis and potential therapeutic targets.
    • Understanding rare genetic inheritance patterns is crucial for genetic counseling and diagnosis in affected families.
