Presentation
The present study was performed to identify the presence of a possible gene mutation as a cause for this syndrome. DNA from peripheral leukocytes was isolated from 15 unaffected and 8 affected individuals from the kindred. [jhu.pure.elsevier.com]
Given the variability in clinical presentation in all patients with RTH, it is difficult to classify patients as having purely PRTH or RTH, as some patients with the identical Tr beta mutation may present with either PRTH or RTH. [endocrinologyadvisor.com]

In the present case, the patient presented this trait, Figure 1, which pointed to a case of central hyperthyroidism, and RTH syndrome was thought to be the cause. [frontiersin.org]
We report on an 8-year-old boy with pituitary resistance to thyroid hormone ( PRTH ) having a cysteine for arginine substitution at codon 320 in the TR-beta gene who was presented because of thyrotoxicosis [11]. [wikigenes.org]

Treatment - Generalized resistance to thyroid hormone Treatment varies vastly from person to person but what is common to all are the high doses of thyroid hormone necessary before a patient feels well. [checkorphan.org]
Failure to recognize this may incorrectly result in antithyroid treatment. [endocrinologyadvisor.com]
Treatment Treatment options for patients with MCT8 gene mutations are currently limited. Supportive measures include the use of braces to prevent mal-positioned contractures that may ultimately require orthopedic surgery. [flipper.diff.org]

The diagnosis may involve identifying a mutation of the thyroid receptor, which is present in approximately 85% of cases Prognosis - Generalized resistance to thyroid hormone Not supplied. [checkorphan.org]

Not always the cause is genetic, so you might suggest a lack of selenium in the diet that prevents the proper functioning of selenoproteins causing the typical symptoms of hypothyroidism. ROTA MARTA BOIETTI EDOARDO [flipper.diff.org]
Through a mechanism of dominant inhibition, the mutated receptor prevents the binding of T3 to its receptor and gives rise to a lesser tissular response to the action of thyroid hormones. [elsevier.es]
Futhermore, genetic counseling can also be provided to those who intend to have consanguineous unions and can help in prevention of the disease. [jmedicalcasereports.biomedcentral.com]
