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 c.1300C>T (p.R434*) alteration, located in exon 12 (coding exon 11) of the DUOX2 gene, consists of a C to T substitution at nucleotide position 1300. This changes the amino acid from a arginine (R) to a stop codon at amino acid position 434. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This alteration has been detected in individuals with congenital hypothyroidism, in the homozygous state and in the heterozygous state without a second alteration identified (Cangul, 2014; Moreno, 2002; Wang, 2020). Based on the available evidence, this alteration is classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Arg434*) 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 (rs119472026, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with autosomal recessive congenital hypothyroidism (PMID: 12110737, 24127536). ClinVar contains an entry for this variant (Variation ID: 4062). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
