Pituitary-thyroid function in Pendred's syndrome. 1974

A Gomez-Pan, and D C Evered, and R Hall

Pendred's syndrome is reported in three siblings. All were euthyroid, with large goitres and deaf mutism and all had an unusual deposition of pigment in the retina. All had raised circulating levels of triiodothyronine (T-3) and an exaggerated response of thyroid-stimulating hormone (TSH) to thyrotrophin-releasing hormone (TRH). It appears that their compensated euthyroid state was maintained by the raised T-3 levels. We suggest that preferential T-3 production is maintained by increased TSH secretion in subjects with intrathyroidal iodine deficiency secondary to thyroid organification defect.

UI	MeSH Term	Description	Entries
D007455	Iodine	A nonmetallic element of the halogen group that is represented by the atomic symbol I, atomic number 53, and atomic weight of 126.90. It is a nutritionally essential element, especially important in thyroid hormone synthesis. In solution, it has anti-infective properties and is used topically.	Iodine-127,Iodine 127
D007457	Iodine Radioisotopes	Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes.	Radioisotopes, Iodine

D010902	Pituitary Gland	A small, unpaired gland situated in the SELLA TURCICA. It is connected to the HYPOTHALAMUS by a short stalk which is called the INFUNDIBULUM.

D005260	Female		Females
D006042	Goiter	Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).	Goiters
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D012168	Retinal Pigments	Photosensitive protein complexes of varied light absorption properties which are expressed in the PHOTORECEPTOR CELLS. They are OPSINS conjugated with VITAMIN A-based chromophores. Chromophores capture photons of light, leading to the activation of opsins and a biochemical cascade that ultimately excites the photoreceptor cells.
