A Berthon , N Settas , A Delaney , A Giannakou , A Demidowich , FR Faucz , SB Seminara , ME Chen , CA Stratakis

Hum Mol Genet. 2020 Dec 18;29(20): 3443–3450.https://pubmed.ncbi.nlm.nih.gov/33089319/The authors performed an experimental study in Kiss1 knock-out mice, followed by an observational study of patients with adrenal tumors. The findings indicate that KISS1/KISS1R signaling may be involved in obesity, metabolic disorders and even gonadal steroid hormone perturbations.<p class="abstex...

JCI Insight. 2020 Oct 27;5(23):e134310. doi: 10.1172/jci.insight.134310. PMID: 33108146.Lodge et al. screened 28 patients with pituitary stalk interruption syndrome (PSIS) for mutations in the FAT/DCHS (FAT atypical cadherin/ Dachsous cadherin-related) family of protocadherins. FAT2 and DCHS2 putative damaging variants were found in 6/28 patients with ectopic ...

To read the full abstract: Cell 2019;177 (3):59–-607.e9. PMID 31002796.A recent GWAS showed that the heritability of thinness was comparable to that of obesity (1). Some loci showed effects across the entire BMI distribution. This is also true for variants in MC4R. The present study analyzed data on ˜0.5 million people from UK Biobank, with a focus on 61 nonsynonymous var...
