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...

Epub 2018 Jul 19https://www.ncbi.nlm.nih.gov/pubmed/30374425Diagnosis and treatment of central hypothyroidism are much more complex than for primary hypothyroidism. For the first time, guidelines summarize all the available evidence to provide a thorough state of...

To read the full abstract: J Clin Endocrinol Metab, March 2020, 105(3):e70–e84A cohort of 21 adult males (aged 19 to 89 years) harboring hemizygous pathogenic IGSF1 gene mutations underwent anthropometry, endocrine testing, testis ultrasonography, and body composition assessment to define the pathophysiological role of IGSF1 in influencing GH secretion. In addition, two lines of Igsf1 -deficient male mice were use...

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...
