    Area of Science:

    • Genetics
    • Human genetics
    • Reproductive biology

    Background:

    • Sex chromosome abnormalities can lead to diverse clinical presentations.
    • Understanding mosaicism is crucial for accurate diagnosis and prognosis.

    Observation:

    • The infant presented with a rare mosaic condition involving 45X and 47XYY karyotypes.
    • Clinical observations were correlated with cytogenetic analysis.

    Findings:

    • Detailed cytogenetic analysis confirmed the 45X/47XYY mosaicism.
    • Specific clinical features associated with this unusual combination were documented.

    Implications:

    • This case expands the understanding of sex chromosome aneuploidies.
    • Further research into 45X/47XYY mosaicism is warranted for improved clinical management.
