Variant summary
Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_001363711.2(DUOX2):c.2524C>T(p.Arg842*) variant causes a stop gained change. The variant allele was found at a frequency of 0.0000186 in 1,614,038 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R842R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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. -
