Genes affected
DIO3 (HGNC:2885): (iodothyronine deiodinase 3) The protein encoded by this intronless gene belongs to the iodothyronine deiodinase family. It catalyzes the inactivation of thyroid hormone by inner ring deiodination of the prohormone thyroxine (T4) and the bioactive hormone 3,3',5-triiodothyronine (T3) to inactive metabolites, 3,3',5'-triiodothyronine (RT3) and 3,3'-diiodothyronine (T2), respectively. This enzyme is highly expressed in pregnant uterus, placenta, fetal and neonatal tissues, and thought to prevent premature exposure of developing fetal tissues to adult levels of thyroid hormones. It regulates circulating fetal thyroid hormone concentrations, and thus plays a critical role in mammalian development. Knockout mice lacking this gene exhibit abnormalities related to development and reproduction, and increased activity of this enzyme in infants with hemangiomas causes severe hypothyroidism. This protein is a selenoprotein, containing the rare selenocysteine (Sec) amino acid at its active site. Sec is encoded by the UGA codon, which normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon rather than as a stop signal.

DIO3OS (HGNC:20348): (DIO3 opposite strand upstream RNA) The mouse and human DIO3OS and DIO3 (MIM 601038) genes overlap and are transcribed in opposite directions. The mouse Dio3 gene is imprinted from the paternal allele during fetal development, suggesting that DIO3OS is a noncoding gene that may have a role in maintaining monoallelic expression of DIO3 (Hernandez et al., 2004 [PubMed 14962667]).[supplied by OMIM, Mar 2008]
