Hum Mol Genet. 2022 May 10:ddac093. doi: 10.1093/hmg/ddac093. Online ahead of print. PMID: 35535691Brief Summary: This genome-wide association study (GWAS) of patients with thyroid dysgenesis identified a genetic risk locus for thyroid athyreosis and ectopy. In depth genetic analyses of the disease associated region suggested a new disease mechanism of thyroid dysgenesis mediated by impaired Wnt ...

To read the full abstract: J Clin Endocrinol Metab 2018;103:1459-1469The ESPE guidelines on CH recommend an initial LT4 dose of 10-15 microgram/kg per day1. Infants with severe CH, defined by a very low pretreatment TT4 or FT4 concentration, should be treated with the highest initial dose. However, little is known about long-term effects on developmental and...

Brief summary: American Thyroid Association Guidelines for management of children with thyroid nodules and differentiated thyroid cancer were published in 2015 (1). Now Lebbink et al. published management guidelines from the European Thyroid Association.Pediatric differentiated thyroid carcinoma is rare. For many aspects of the disease (diagnosis, treatment, follow-up) clear evidence from randomized controlled trials are therefore missing. The p...
