Abstract
Nineteen families with hereditary abnormalities of thyroxine-binding globulin (TBG) were studied, comprising 15 males with absent TBG, 15 females heterozygotic for this condition, 14 males with excess of TBG and 44 heterozygotic females. Hereditary TBG excess was associated with thyrotoxicosis in 4 instances, and with myxedema in 3. The typical biochemical features of TBG abnormality are described, with the clinical histories of patients in whom diagnostic and management problems occurred.
