T. Noguchi et al., HEREDITARY COMPLETE THYROXINE-BINDING GLOBULIN DEFICIENCY - IDENTIFICATION BY T(3) RESIN UPTAKE TEST AND DNA ANALYSIS, Japanese journal of medicine, 32(1), 1993, pp. 6-9
Complete thyroxine-binding globulin deficiency (TBG-CD) was uncovered
in a subject receiving a comprehensive health examination. The subject
had an abnormally high T3 resin uptake. A family study showed that th
e TBG abnormality had been inherited by X-chromosome linkage. Genetic
analysis revealed single nucleotide deletion, common among Japanese wi
th TBG-CD, from the allele specific amplification of the TBG genes of
the family.
