Genetically determined thyroxine-binding globulin deficiency is described in two families in the United Kingdom. All subjects in both pedigrees were euthyroid. Transmission was by sex-linkage; males showed low serum protein bound iodine and high thyroxine (T4) resin uptake due to complete absence of serum thryroxine-binding globulin; females were less severely affected. The distinctive biochemical results disclosed the diagnosis and emphasize that serum protein bound iodine levels should be interpreted carefully and tests, such as triiodothyroinine (T3) or T4 resin uptake, used to prevent erroneous diagnoses of hypothyroidism.
在英国的两个家族中发现了遗传性甲状腺素结合球蛋白缺乏症。两个家系中的所有受试者甲状腺功能均正常。该病通过性连锁遗传;男性由于完全缺乏血清甲状腺素结合球蛋白,血清蛋白结合碘水平低,甲状腺素(T4)树脂摄取率高;女性受影响程度较轻。这些独特的生化结果揭示了该诊断,并强调应谨慎解释血清蛋白结合碘水平,以及用于预防甲状腺功能减退症错误诊断的检测方法,如三碘甲状腺原氨酸(T3)或T4树脂摄取试验。
