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]

The R842X variant in the DUOX2 gene has been reported previously as compound heterozygous in unrelated individuals with transient or persistent congenital hypothyroidism (Vigone et al., 2005; Fu et al., 2015). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R842X variant is observed in 14/277130 (0.005%) alleles in large population cohorts, and no individuals were reported to be homozygous (Lek et al., 2016). We interpret R842X as a pathogenic variant. -

This sequence change creates a premature translational stop signal (p.Arg842*) in the DUOX2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DUOX2 are known to be pathogenic (PMID: 12110737, 18765513, 21565790, 24423310, 24735383). This variant is present in population databases (rs119472028, gnomAD 0.008%). This premature translational stop signal has been observed in individual(s) with autosomal recessive thyroid dyshormonogenesis (PMID: 16134168, 27108200). ClinVar contains an entry for this variant (Variation ID: 4064). For these reasons, this variant has been classified as Pathogenic. -
