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 pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Jun 22, 2023	Reported in the homozygous and heterozygous states in individuals with congenital hypothyroidism (CH) or thyroid dyshormonogenesis (DH), however many affected individuals harbored one or more additional variants in DUOX2 and/or other CH- or DH-associated genes, making it difficult to determine the pathogenicity of this variant (Fu et al., 2015; Fu et al., 2016; Fan et al., 2017; Chen et al., 2018; Jiang et al., 2016; Peters et al., 2019); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In silico analysis suggests this variant may impact gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; This variant is associated with the following publications: (PMID: 34539567, 29779043, 27256230, 27173810, 29146476, 31356790, 26349762, 27108200, 28215547, 30022773, 30154845, 27498126, 31044655, 32425884, 33631011, 33490161, 33628596, 33310921, 36207832, 37147621, 34767783, 36555929) -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
