ractText>Mutations of the whole coding region of the TUBB1 gene were analyzed for 289 children with CH and TD in BACKGROUND
Although thyroid dysgenesis is the most common cause of congenital hypothyroidism (CH), its molecular basis remains largely elusive. Indeed, in only a minority of cases with thyroid dysgenesis (2%-3%) was it possible to identify an underlying genetic defect. The objective of this study
BACKGROUND
Thyroid dysgenesis is the most frequent cause of congenital hypothyroidism (CH), and its genetic basis is largely unknown. Hitherto, two mutations in the human thyroid transcription factor 2 (TTF-2) gene have been described in unrelated cases of CH with cleft palate, spiky hair, variable
A growth-retarded, mentally deficient, young man is described with diminished secretory response of growth hormone, thyrotropin, and prolactin to the pharmacologic stimuli of insulin, arginine, chlorpromazine, and thyrotropin-releasing hormone. Gonadotropin and ACTH functions were normal both
BACKGROUND
Congenital hypothyroidism (CH) is a neonatal endocrine disease with an incidence of 1:2000 to 1:4000 worldwide. In about 85% of patients CH is secondary to thyroid dysgenesis, but its pathogenesis remains unclear. Thyroid transcription factors, such as paired box transcription factor 8
