thyroid hormone receptor beta

From NCBI Gene:
The protein encoded by this gene is a nuclear hormone receptor for triiodothyronine. It is one of the several receptors for thyroid hormone, and has been shown to mediate the biological activities of thyroid hormone. Knockout studies in mice suggest that the different receptors, while having certain extent of redundancy, may mediate different functions of thyroid hormone. Mutations in this gene are known to be a cause of generalized thyroid hormone resistance (GTHR), a syndrome characterized by goiter and high levels of circulating thyroid hormone (T3-T4), with normal or slightly elevated thyroid stimulating hormone (TSH). Several alternatively spliced transcript variants encoding the same protein have been observed for this gene. [provided by RefSeq, Jul 2008]
Nuclear hormone receptor that can act as a repressor or activator of transcription. High affinity receptor for thyroid hormones, including triiodothyronine and thyroxine.
From NCBI Gene:
- Thyroid hormone resistance, selective pituitary
- Thyroid hormone resistance, generalized, autosomal recessive
- Thyroid hormone resistance, generalized, autosomal dominant
Generalized thyroid hormone resistance (GTHR): A disease characterized by goiter, abnormal mental functions, increased susceptibility to infections, abnormal growth and bone maturation, tachycardia and deafness. Affected individuals may also have attention deficit-hyperactivity disorders (ADHD) and language difficulties. GTHR patients also have high levels of circulating thyroid hormones (T3-T4), with normal or slightly elevated thyroid stimulating hormone (TSH). [MIM:188570]
Generalized thyroid hormone resistance autosomal recessive (GTHRAR): An autosomal recessive disorder characterized by goiter, clinical euthyroidism, end-organ unresponsiveness to thyroid hormone, abnormal growth and bone maturation, and deafness. Patients also have high levels of circulating thyroid hormones, with elevated thyroid stimulating hormone. [MIM:274300]
Selective pituitary thyroid hormone resistance (PRTH): Variant form of thyroid hormone resistance and is characterized by clinical hyperthyroidism, with elevated free thyroid hormones, but inappropriately normal serum TSH. Unlike GRTH, where the syndrome usually segregates with a dominant allele, the mode of inheritance in PRTH has not been established. [MIM:145650]
