View Organification Defect Thyroid PNG. The classification of defective organification of iodide is primarily based on the site of the biochemical defect, being quantitative (tpo absent) or qualitative (tpo structure, localization or apoenzyme are defectives). (redirected from thyroid hormone organification defect iia) thyroid dyshormonogenesis 2a an endocrinopathy (omim:274500) caused by defective conversion of iodide to organically bound iodine (organification), which can be partial or complete.
Maternal Fetal Transfer Of Thyroxine In Congenital Hypothyroidism Due To A Total Organification Defect Or Thyroid Agenesis Nejm from www.nejm.org Direct sequencing of their genomic dnas showed two novel mutations of the tpo gene, one of which was g1687t (gly533cys; This release of radioiodide represents total iodine organification defect (tiod), a disruption of the process by which iodide present in the thyroid is oxidized by hydrogen peroxide and bound to tyrosine residues in thyroglobulin (tg; Congenital hypothyroidism is usually sporadic but up to 2% of thyroid dysgenesis is familial, and congenital hypothyroidism caused by organification defects is often recessively inherited.
Mutations in the thyroid peroxidase (tpo) gene lead to severe congenital hypothyroidism due to total iodide organification defect (tiod).
This condition, clinically called pendred syndrome, is the hereditary association of congenital deafness (deafness at the time of birth) and goiter (enlargement of the thyroid gland in the front of the neck) due to a defect in the making of… The two mutations were compound heterozygous, as the former was found in. Tpo mutations are one of the most frequent causes of thyroid dyshormonogenesis. A follicular adenoma of the thyroid was 'hot' one hour after 99m tc pertechnetate administration, but 'cold'24 h after 131 i iodide administration.
