    This study reports a patient with abnormal cortisol binding globulin (CBG). Despite normal CBG levels, reduced binding affinity may contribute to adrenocortical hyperfunction.

    Area of Science:

    • Endocrinology
    • Protein biochemistry

    Background:

    • Cortisol binding globulin (CBG) plays a crucial role in regulating cortisol bioavailability.
    • Abnormalities in CBG can affect endocrine function and hormone-related conditions.

    Observation:

    • A patient presented with an apparent abnormality of cortisol binding globulin (CBG).
    • Plasma CBG binding capacity was found to be normal, indicating typical CBG concentration.

    Findings:

    • The patient's plasma CBG exhibited a fourfold reduction in binding affinity for cortisol.
    • This suggests a qualitative defect in CBG function rather than a quantitative one.

    Implications:

    • Reduced CBG binding affinity may have significant physiological consequences.

  • This finding could be relevant to the development of adrenocortical hyperfunction observed in the patient.
  • Further research is warranted to elucidate the precise role of altered CBG binding in endocrine disorders.
