Genes affected

DUOX2 (HGNC:13273): (dual oxidase 2) The protein encoded by this gene is a glycoprotein and a member of the NADPH oxidase family. The synthesis of thyroid hormone is catalyzed by a protein complex located at the apical membrane of thyroid follicular cells. This complex contains an iodide transporter, thyroperoxidase, and a peroxide generating system that includes this encoded protein and DUOX1. This protein is known as dual oxidase because it has both a peroxidase homology domain and a gp91phox domain. [provided by RefSeq, Jul 2008]

Likely benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

research

Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard

The heterozygous p.Ala728Thr variant in DUOX2 has been identified in an individual with congenital hypothyroidism (PMID: 21565790), and has been identified in >1% of Latino chromosomes and 7 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In vitro functional studies provide some evidence that the p.Ala728Thr variant may not impact protein function (PMID: 21565790). However, these types of assays may not accurately represent biological function. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely benign for autosomal recessive congenital hypothyroidism. -
