Genes affected
DUOXA2 (HGNC:32698): (dual oxidase maturation factor 2) This gene encodes an endoplasmic reticulum protein that is necessary for proper cellular localization and maturation of functional dual oxidase 2. Mutations in this gene have been associated with thyroid dyshormonogenesis 5.[provided by RefSeq, Feb 2010]

Pathogenic, criteria provided, single submitterclinical testingInvitaeFeb 08, 2018This sequence change creates a premature translational stop signal (p.Leu32Phefs*78) in the DUOXA2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DUOXA2 are known to be pathogenic (PMID: 18042646, 23292166, 25675383). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with DUOXA2-related disease. For these reasons, this variant has been classified as Pathogenic. -
