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]

Pathogenic:2

Likely pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Feb 27, 2023	Published functional studies demonstrate a damaging effect (Grasberger et al., 2007); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 31589614, 30240412, 34200080, 33490161, 16134168, 22336364, 33651715, 21704604, 17374849, 32319661, 33562188) -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 14, 2024	This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 376 of the DUOX2 protein (p.Arg376Trp). This variant is present in population databases (rs119472029, gnomAD 0.02%). This missense change has been observed in individual(s) with congenital hypothyroidism (PMID: 16134168, 22336364, 30240412). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 4065). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DUOX2 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects DUOX2 function (PMID: 17374849). For these reasons, this variant has been classified as Pathogenic. -

PreventionGenetics, part of Exact Sciences

Apr 11, 2023

The DUOX2 c.1126C>T variant is predicted to result in the amino acid substitution p.Arg376Trp. This variant has been reported in the compound heterozygous state in two siblings with persistent mild hypothyroidism (Vigone et al. 2005. PubMed ID: 16134168) and in another individual with congenital hypothyroidism (Patients ID: 16, Wang et al. 2020. PubMed ID: 32319661). This variant has also been reported in the heterozygous state in an individual with congenital hypothyroidism (N45, Makretskaya et al. 2018. PubMed ID: 30240412). This variant is reported in 0.016% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/15-45402093-G-A) and is reported as pathogenic/likely pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/4065/). This variant is interpreted as likely pathogenic. -
