    Ataxia-telangiectasia is a rare genetic disorder causing cerebellar ataxia and immune deficiencies. This study details two cases, highlighting varied clinical presentations and autopsy findings, including ovarian tumors and pulmonary fibrosis.

    Area of Science:

    • Genetics
    • Neurology
    • Immunology

    Background:

    • Ataxia-telangiectasia (A-T) is a complex syndrome characterized by progressive cerebellar ataxia, oculocutaneous telangiectasias, and recurrent sinopulmonary infections.
    • Associated immunological and endocrine abnormalities are frequently observed in A-T patients.
    • Understanding the multifaceted nature of A-T is crucial for diagnosis and management.

    Purpose of the Study:

    • To describe the clinical, immunological, and pathological findings in two girls diagnosed with ataxia-telangiectasia.
    • To investigate the spectrum of manifestations and complications associated with this rare genetic disorder.
    • To contribute to the existing literature on ataxia-telangiectasia through detailed case reports.

    Main Methods:

    • Case study methodology involving detailed clinical observation and medical history.

  • Immunological assessment including serum protein analysis and immune response evaluation.
  • Post-mortem examination including histopathological analysis of affected organs.

    • Main Results:

    • The first patient presented with mild respiratory infections and normal immunological parameters.
    • The second patient experienced recurrent pulmonary infections, bronchiectasis, endocrine abnormalities (hypogonadism, low 17-ketosteroids), lymphopenia, and sclerodermatous changes.
    • Autopsy revealed ovarian dysgerminomas, pulmonary fibrosis, cerebellar degeneration, and lymphoid tissue hypoplasia in the second patient.

    Conclusions:

    • Ataxia-telangiectasia exhibits a wide range of clinical variability, affecting neurological, immunological, and endocrine systems.
    • Pulmonary complications and the potential for malignancy (e.g., ovarian tumors) are significant concerns in A-T.
    • Detailed pathological findings underscore the systemic nature of the disease and the need for comprehensive patient care.
