Brief summary: Using data on 4964 type 1 diabetes (T1D) cases and 7497 controls, this study assessed whether the effect of common genetic variants (SNPs) on risk of T1D is mediated through trans-effects on the expression of core genes. Nine putative core genes were identified, all implicated in immune system regulation. In addition, four T1D-associated genomic regions were identified as master regulators that have trans-effects on gene expression.<p class="abstext...

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 ...

PMID: 32197072.In brief: High-sugar diets cause thirst, obesity and metabolic dysregulation, leading to insulin resistance, the MetS, T2DM and shortened lifespan. This study shows that high sugar diets induce dehydration in adult Drosophila. Water supplementation fully rescued the shortened lifespan, but ...

Epub 2022 Mar 21.Brief Summary: Currently, preimplantation genetic testing (PGT) is used to avoid specific rare Mendelian disorders before in-vitro fertilization (IVF). However, evidence is limited on the potential use of a polygenic risk score (PRS) that combines thousands of genetic variants as a predictor fo...

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...

To read the full abstract: Pediatr Diabetes. 2018;19:1471–1480It has been debated whether or not new technologies, in particular the combination of insulin pumps and continuous glucose testing, will improve patient satisfaction and quality of life rather than only metabolic control and risk of microvascular complications. Indeed, the use of continuous subcutaneous insulin infusion (...
