Partial D 15 trisomy. A case and general review.

W R Centerwall, J P Morris

    Human Heredity
    |January 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    This study identifies a rare genetic condition in a girl with developmental delays and heart disease. The extra chromosome was identified as a partially deleted chromosome 15, contributing to her unique clinical presentation.

    Area of Science:

    • Genetics
    • Clinical Medicine
    • Cytogenetics

    Background:

    • Congenital heart disease and developmental delays can stem from various genetic anomalies.
    • Accurate chromosomal identification is crucial for understanding rare genetic disorders.

    Observation:

    • A girl presented with profound intellectual disability, cyanotic congenital heart disease, myoclonic seizures, and strabismus.
    • Karyotype revealed an extra small G-size chromosome with unique features, including projections on the long arms.

    Findings:

    • Giemsa-trypsin banding identified the extra chromosome as a partially deleted chromosome 15.
    • This case aligns with 'partial trisomy 15' but presents distinct morphological characteristics.

    Implications:

    Related Experiment Videos

    • This case expands the understanding of partial trisomy 15 phenotypes.
    • The findings highlight the importance of detailed cytogenetic analysis in diagnosing complex genetic syndromes.
