Summaries for Thyroid Dyshormonogenesis 1

OMIM : 53 Approximately 10% of patients with congenital hypothyroidism harbor inborn errors of metabolism in one of the steps for thyroid hormone synthesis in thyrocytes (Vono-Toniolo et al., 2005). Dyshormonogenesis can be caused by recessive defects at any of the steps required for normal thyroid hormone synthesis. In untreated patients thyroid dyshormonogenesis is typically associated with goitrous enlargement of the thyroid secondary to long-term thyrotropin (TSH; see 188540) stimulation. Park and Chatterjee (2005) reviewed the genetics of primary congenital hypothyroidism, summarizing the different phenotypes associated with known genetic defects and proposing an algorithm for investigating the genetic basis of the disorder. (274400)

MalaCards based summary : Thyroid Dyshormonogenesis 1, also known as tdh1, is related to pendred syndrome, and has symptoms including constipation, lethargy and dry skin. An important gene associated with Thyroid Dyshormonogenesis 1 is SLC5A5 (Solute Carrier Family 5 Member 5). Affiliated tissues include thyroid and skin.

UniProtKB/Swiss-Prot : 71 Thyroid dyshormonogenesis 1: A disorder characterized by the inability of the thyroid to maintain a concentration difference of readily exchangeable iodine between the plasma and the thyroid gland, leading to congenital hypothyroidism.
