FT4 estimation by equilibrium dialysis excluded analytical interference, and molecular analysis for the thyroid hormone receptor β gene associated with thyroid hormone resistancewas negative.
The first case of association between postpartum thyroiditis and thyroid hormone resistance in an Italian patient showing a novel p.V283ATHRB mutation.
We present 1 pedigree of THRS with heterozygous A317T mutation in THRβ gene in the proband and his mother, which is the first reported mutation in Chinese and provides a comprehensive review of available literature.
This insertion mutation, specifically the insertion of a cytosine at nucleotide 1358 of the THRB gene, is, to the best of our knowledge, the first such mutation reported among RTH patients in Korea.
In almost all cases it is due to different mutations in only one allele of the thyroid hormone receptor beta gene which blocks the action of normal allele thus producing dominantly inherited RTH.
Periodically hyperthyroid phenotype in thyroid hormone resistance is associated with mutation D322N in the thyroid hormone receptor beta gene: transcriptional properties of the mutant and the role of retinoid X receptor.
Enhanced levels of wild-type versus mutant thyroid hormone receptor beta 1 messenger RNA in fibroblasts from heterozygotes of kindred S with thyroid hormone resistance.
Rapid localization of mutations in the thyroid hormone receptor-beta gene by denaturing gradient gel electrophoresis in 18 families with thyroid hormone resistance.
Tissue responses to thyroid hormone in a kindred with resistance to thyroid hormone harboring a commonly occurring mutation in the thyroid hormone receptor beta gene (P453T).
To document an infant with a cone photoreceptor disorder associated with severe thyroid hormone resistance due to compound heterozygosity in the thyroid hormone receptor beta 2 (TRβ2) encoding gene THRβ2.
Resistance to thyrotropin (TSH) (RTSH; defined by elevated TSH and a normal or hypoplastic thyroid gland) can be caused by mutations in genes encoding the TSH receptor and PAX8, and it has been linked to a locus on chromosome 15.
Nonpolymorphic alterations in the TSHR gene are commonly associated with isolated NAHT in young patients, thus configuring partial TSH resistance as the most frequent inheritable cause of isolated NAHT.
Complete TSH resistance due to biallelic LOF TSHR mutations must be suspected in all patients with severe not syndromic CH and severe thyroid hypoplasia diagnosed at birth by neonatal screening.
