Monogenic Diabetes

The Monogenic Diabetes group is a multi-disciplinary group of Molecular Geneticists, Data scientists, Bioinformaticians, Clinical Scientists, Doctors, and Nurses. Its mission is to improve understanding and clinical care of monogenic diabetes.

The group's expertise is in Gene discovery, genomics, physiology, treatment response, diagnostic modelling, pharmacogenetics, and experimental medicine, and its research is aimed at:

• Defining the genetic aetiology of novel subtypes of monogenic diabetes
• Defining the clinical features, and pathophysiology of monogenic diabetes
• Developing the best approaches to diagnosis of monogenic diabetes (both clinical and molecular genetic)
• Optimising education, treatment and management for patients living with monogenic diabetes
• Using monogenic diabetes to understand physiology and broader concepts
• Understanding the relationship between monogenic diabetes and Type 1 and Type 2 diabetes.

Landmark papers

Activating germline mutations in STAT3 cause early-onset multi-organ autoimmune disease.
Flanagan SE, Haapaniemi E, Russell MA, Caswell R, Allen HL, De Franco E, McDonald TJ, Rajala H, Ramelius A, Barton J, Heiskanen K, Heiskanen-Kosma T, Kajosaari M, Murphy NP, Milenkovic T, Seppänen M, Lernmark Å, Mustjoki S, Otonkoski T, Kere J, Morgan NG, Ellard S, Hattersley AT. Nat Genet. 2014 Aug;46(8):812-814. PMID: 25038750 >310 citations. This was amongst the first studies to use next-generation sequencing to find a novel monogenic diabetes gene. The results highlighted a role for STAT3 in beta cell autoimmunity and/or pancreatic development.

Switching from insulin to oral sulfonylureas in patients with diabetes due to Kir6.2 mutations.
Pearson ER, Flechtner I, Njolstad PR, Malecki MT, Flanagan SE, Larkin B, Ashcroft FM, Klimes I, Codner E, Iotova V, Slingerland AS, Shield J, Robert JJ,Holst JJ, Clark PM, Neonatal Diabetes International Collaborative Group, Ellard S, Sovik O, Polak M*, Hattersley AT
N England J Med 2006;3:467-77 PMID: 16885550 >950 citations. This study dramatically changed patient care for children with neonatal diabetes as 90% of insulin-dependent patients with Kir6.2 mutations could transfer from insulin injections to sulphonylurea tablets and improve their glycaemic control. In accompanying physiological studies we established the key role of non-KATP pathways as the predominant mechanism of action

Recessive mutations in a distal PTF1A enhancer cause isolated pancreatic agenesis.
Weedon MN, Cebola I, Patch AM, Flanagan SE, De Franco E, Caswell R, Rodríguez-Seguí SA, Shaw-Smith C, Cho CH, Lango Allen H, Houghton JA, Roth CL, Chen R, Hussain K, Marsh P, Vallier L, Murray A; International Pancreatic Agenesis Consortium, Ellard S, Ferrer J, Hattersley AT. Nat Genet. 2014 Jan;46(1):61-4 PMID: 24212882 >220 Citations. This is the first study to identify novel disease-causing non-coding variants by combining genome sequencing with epigenomic annotation in hESC-derived pancreatic progenitors. We showed mutations which disrupt a, previously unrecognised, regulatory enhancer of PTF1A is the most common cause of isolated pancreatic agenesis.
