Congenital hypothyroidism can also occur due to genetic defects of thyroxine or triiodothyronine synthesis within a structurally normal gland. Among specific defects are thyrotropin ( TSH ) resistance, iodine trapping defect, organification defect, thyroglobulin , and iodotyrosine deiodinase deficiency.
Thyroid dysgenesis is a cause of congenital hypothyroidism [1] where the thyroid is missing (thyroid agenesis), ectopic, or severely underdeveloped.It should not be confused with iodine deficiency, or with other forms of congenital hypothyroidism, such as thyroid dyshormonogenesis, where the thyroid is present but not functioning correctly.
The most commonly included disorders of the endocrine system are congenital hypothyroidism (CH) and congenital adrenal hyperplasia (CAH). [20] Testing for both disorders can be done using blood samples collected on the standard newborn screening card. Screening for CH is done by measuring thyroxin (T4), thyrotropin (TSH) or a combination of ...
While TSH-based screening will identify the most common causes, the addition of T 4 testing is required to pick up the rarer central causes of neonatal hypothyroidism. [30] If T 4 determination is included in the screening done at birth, this will identify cases of congenital hypothyroidism of central origin in 1:16,000 to 1:160,000 children.
Congenital iodine deficiency has been almost eliminated in developed countries through iodine supplementation of food and by newborn screening using a blood test for thyroid function. [5] Treatment consists of lifelong administration of thyroxine (T4). Thyroxine must be dosed as tablets only, even to newborns, as the liquid oral suspensions and ...
The following disorders are additional conditions that may be detected by screening. Many are listed as "secondary targets" by the 2005 ACMG report. [1] Some states are now screening for more than 50 congenital conditions. Many of these are rare and unfamiliar to pediatricians and other primary health care professionals. [1] Blood cell disorders
