Competitive polymerase chain reaction quantitation of c-erbA beta 1, c-erbA alpha 1, and c-erbA alpha 2 messenger ribonucleic acid levels in normal, heterozygous, and homozygous fibroblasts of kindred S with thyroid hormone resistance.

Abstract excerpt

Mutations in the T3-binding domain of the thyroid hormone receptor gene c-erbA beta result in dominant negative proteins and thyroid hormone resistance syndromes. Variable clinical manifestations of resistance to thyroid hormones have been reported, including short stature and neuropsychological abnormalities. The molecular bases for heterogeneity of phenotype among and within kindreds have not been fully...
