The Role of HNF1B in Human Pancreas Development and Diabetes

El Khairi Ranna , Hattersley Andrew , Vallier Ludovic

Background: Diabetes mellitus is a heterogeneous disorder with multiple aetiologies. Monogenic diabetes accounts for an estimated 2–5% of cases and is often associated with impaired pancreas development and β-cell dysfunction. Heterozygous mutations in the transcription factor, HNF1B, result in multi-system disease including diabetes due to β-cell dysfunction, hepatic insulin resistance and pancreatic hypoplasia. However, the mechanisms that underlie development...

First Four Cases of Neonatal Diabetes from Kazakhstan, Almaty with Proven Mutations in KCNJ11 and INS Genes

Nurbekova Akmaral , Hattersley Andrew , Ten Svetlana , Bhangoo Amrit

We report three cases of neonatal diabetes from Kazakhstan, Almaty with the KCNJ11 gene mutation who were successfully switched from insulin to sulphonylurea treatment and 1 case of insulin (INS) gene mutation that presented as permanent insulin dependent neonatal diabetes.Case 1: An 1 month old girl presented with elevated glucose level, dehydation, ketoacidosis and was treated with Insulin. HbA1c at diagnosis was 10%. Heterozygous missense mut...

First 2 Cases of Monogenic Diabetes (MODY) from Kazakhstan, Almaty with Proven Heterozygous Mutation in Hepatocyte Nuclear Factor 1-Alpha (HNF1A) Gene

Nurbekova Akmaral , Hattersley Andrew , Ten Svetlana , Bhangoo Amrit

Background: It is important to make correct diagnosis of monogenic diabetes or MODY in children. Most of the patients are misdiagnosed with diabetes type 1 or type 2 and undergo unnecessary treatment with insulin or oral medications. We report first 1 case of MODY with heterozygous mutation in HNF1A gene when Insulin treatment was changed to sulphonylurea treatment and 1 case of compound heterozygote of glucokinase (GCK) gene and HNF1A gene mutations.Cas...

A Boy with Diazoxide Unresponsive Congenital Hyperinsulinism due to a Homozygous ABCC8 Missense Mutation Previously Reported to be Dominant

Galcheva Sonya , Iotova Violeta , Flanagan Sarah E , Ellard Sian , Hattersley Andrew

Background: Congenital hyperinsulinism possesses considerable clinical heterogeneity attributed partly to its diverse genetic causes.Objective: To present a boy with diazoxide unresponsive hyperinsulinaemic hypoglycaemia due to a homozygous recessive ABCC8 missense mutation, previously reported to be dominant acting and being inherited by his unaffected heterozygous parents.Material and results: The boy was a third preterm child of...

Neonatal Diabetes in Ukraine

Globa Eugenia , Zelinska Nataliya , Temple Karen , Mackay Deborah , Hattersley Andrew , Flanagan Sarah , Ellard Sian

Background: We established a neonatal section of the Ukrainian Pediatric Diabetes Registry (UPDR) to identify cases of neonatal diabetes (ND).Objective and hypotheses: We investigated the genetic etiology and treatment of patients with ND.Method: According to the UPDR the number of children (0–17 y.o) with DM1 in 2015 was 8388 (a prevalence of one in 907), with DM2 – 36 (one in 211519) and with ND – 52 (one in 146436...

Clinical Case of Cystic Fibrosis-like and APECED-like Syndrome due to Gain-of-Function Variant in STAT1

Vasilev Teodor , Johnson Matthew , Yaneva Natasha , Slavcheva Olga , Modeva Iskra , Hattersley Andrew , Savova Radka ,

Background: STAT1 mutations can cause an extensive spectrum of disease, varying from severe bacterial and viral infections to mild disseminated mycobacterial disease, also chronic mucocutaneous candidiasis. Many patients present with autoimmune manifestations as type 1 diabetes, hypothyroidism and systemic lupus erythematosus. There are risks of cancers and cerebral aneurysms.Aim: To present the clinical manifes...

An Infant with a Novel Kir6.2 Mutation Causing Neonatal Diabetes and Unexplained Lack of Response to Sulphonylurea

O'Connell Susan M , Mc Donald Aoife , O'Toole Norma , Bradfield Anne , Bradley Maura , Hattersley Andrew , Ellard Sian , Proks Peter , Mattis Katia K , Ashcroft Frances , O'Riordan Stephen M P

Background: Neonatal diabetes (NDM) is defined as diabetes developing before 6 months of age, affecting one in 100 000 live births. Permanent NDM is diagnosed in the first 6 months of life with no remission. The majority have a mutation in the ATP-sensitive potassium (KATP) channel (KCNJ11 in 31%, ABCC8 in 13%). Autosomal dominant and recessive forms are described. The majority of patients with NDM caused by KATP mutations respond to sulphonylureas.<p...
