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]

DUOXA2 Gene-Disease associations (from GenCC):

• thyroid dyshormonogenesis 5

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics
• familial thyroid dyshormonogenesis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
