To read the full abstract: Thyroid. 2019;29:790–801.Patients with mutations in the dual oxidase 2 (DUOX2 ) gene – encoding a NADPH oxidase that generates hydrogen peroxidase for iodide organification – have been repeatedly reported as not being detected by neonatal screening because it causes only mild hyperthyrotropinemia at birth. Here, Peters et al. determined the incidence of DUOX2 and dual oxidase 2...

To read the full abstract: JCI Insight. 2018 Oct 18;3(20). pii: 99631.This paper describes a new form of goitrous congenital hypothyroidism associated with mutations in the solute carrier family 26 member 7 gene (SLC26A7) in 6 unrelated families. In patients, a partial iodide organification defect (PIOD) with normal iodide uptake was observed, hence these mutations cause a new f...
