Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...

TRIAC Treatment of Allan-Herndon-Dudley Syndrome (AHDS) due to Defects in Thyroid Hormone Transporter MCT8

Background: AHDS is a devastating disease caused by defects in the thyroid hormone (TH) transporter MCT8. Endocrine expression is heralded by systemic hyperthyroidism with elevated serum T3, mildly increased TSH and decreased T4. However, the brain is hypothyroid, causing severe psychomotor retardation. Therapeutic attempts with PTU+levothyroxine or the T3-analogue DITPA could normalize TH derangements but without any neurological improvement. ...
