To read the full abstract: Lancet 218; 392: 451–530Despite great improvements in diabetes care, people with type 1 diabetes (T1D) remain at increased risk of mortality and morbidity, in particular from cardiovascular disease (CVD). How exactly diabetes leads to CVD and which factors contribute to the increased risk profile is still largely unknown. Molecular mechanisms are being stu...

I Akerman , MA Maestro , E De Franco , V Grau , S Flanagan , J Garcia-Hurtado , G Mittler , P Ravassard , L Piemonti , S Ellard , AT Hattersley , J Ferrer

Cell Rep. 2021 Apr 13;35(2):108981. doi: 10.1016/j.celrep.2021.108981. PMID: 33852861.Mutations in the promotor region of the insulin gene are associated with a subtype of neonatal diabetes mellitus (NDM). These mutations lead to abnormal transcription of the insulin gene and do so by deleting the C1 and E1 cis regulatory elements, or three different single base-pair substitutions in ...

PMID: 31908791Understanding of the molecular mechanisms underlying neonatal diabetes mellitus (NDM) has helped to transform the clinical management of some patients. Those with NDM due to mutations in the KCNJ11/ABCC8 genes can now be switched to oral sulphonylurea treatment and their daily insu...

Diabetes Care. 2021 Jan;44(1):35–42. doi: 10.2337/dc20-1520. PMID: 33184150.The key findings from this cohort of patients with ABCC8 neonatal diabetes mellitus (NDM) are: A) good glycaemic control is maintained over the long-term without any serious adverse events (including severe hypoglycaemia) despite high doses of sulphonylurea, B) some patients show improvements in neurologica...

Diabetes Care. 2020; 43:82–89. doi: 10.2337/dc19-0747.It is often difficult to identify maturity-onset diabetes of the young (MODY) in pediatric patients close to diabetes onset. Hence, misdiagnosis and unnecessary insulin treatment are still common.This study reports the discriminatory clinical features at diabetes onset in Swedish pediatric patients (age 1–18 y...

However, 10-15% of affected infants do not have a pathogenic variant in one of the 26 known neonatal diabetes genes. In this study, 166 infants diagnosed at <6 months of age without such pathogenic variants showed all the the classic feat...
