To read the full abstract: J Clin Invest. 2020;130:1479–1490.This detailed genetic and molecular analysis of a three-generation family reveals a new form of autosomal dominant tumor susceptibility syndrome entitled familial multinodular goiter (MNG) with schwannomatosis. Biallelic alterations of the DGCR8 gene were found in all affected patients: First, all patients harbored the same heterozygous germline mutation p.E518K. Secondly...

To read the full abstract: Nat Med. 2017 Dec; 23(12): 1444–1453This study highlights the importance of asprosin in the regulation of appetite. This peptide hormone was first described by Romere et al. in 2016 (1), who reported 2 patients with neonatal progeroid syndrome (NPS) due to truncating heterozygous mutations in the fibrillin-gene (FBN1). The FBN1 gene encodes profibrillin wh...

To read the full abstract: Science 2018;359:1376-1383The metabolic syndrome (MetS) is associated with dysfunctions of the intestinal barrier, leading to increased permeability and translocation of microbial molecules into the intestinal lamina propria and to circulation. The entry of pathogens through an impaired barrier leads to an increased risk of infection, as well as to chronic inflammation...

To read the full abstract: Science 2018;360:1087-1092During the Cardiovascular Risk Survey in western China, a Kazakh family with inherited low levels of LDL-C was identified. The Kazakhs are mainly descendent from the Turkic and medieval Mongol peoples, they live in isolated regions and usually marry within their own ethnic group. They exhibit often unique differences in single nucleotide vari...

Brief summary: This randomized, multicenter, controlled, phase II study compared the effects of high-dose (HD) once-weekly PEGylated-recombinant human growth hormone (PEG-rhGH) to low-dose (LD) and to an untreated control group of children with idiopathic short stature (ISS) over a period of 52 weeks. PEG-rhGH was effective in increasing height gain in a dose dependent manner with both doses being well tolerated during the observation period.PEG-rhGH is ...
