China Monogenic Diabetes Registry

This observational study aims to establish a digital registry, screening platform for patients with monogenic diabetes using internet-based and mobile application technologies. The primary objectives are to: Characterize the genetic landscape of monogenic diabetes in the Chinese population, including pathogenic variants and their distribution Participants will: * Enroll in the monogenic diabetes registry via mobile application or web-based platform * Undergo molecular genetic testing to establish a definitive diagnosis

Understanding Beta Cell Disorders Through the Study of Rare Genotypes (ENDURE)

This observational 'recruit by genotype' study aims to provide insights into the cellular and molecular pathways underlying beta cell disorders and their physiological consequences. Eligible individuals are those with and without a pathogenic genetic variant, acting as case and control, respectively. Using a "recruit by genotype" approach, the researchers will perform detailed and specific analysis according to the individual's genetic variant. The study's main aims are to : 1) identify and describe biomarkers and cellular features in blood samples that occur because of the rare causal genetic variant; 2) study the altered physiology or cellular function that are due to the rare causal genetic variant. Participants will attend a study visit that will entail: * Consent * Data collection * Height and weight measures * Blood samples * MRI (optional), dependent on genotype and sub-study objectives. There is no treatment and the participants' normal clinical care will be unaffected and will continue uninterrupted. A small subset of participants may be invited for further sub-studies in the future. Researchers may recruit sex-matched healthy controls (without the variant of interest) with similar age and BMI (age: +/-15%, BMI: +/- 3 kg/m2) for specified case-control studies.

Glucokinase Activator in Monogenic Diabetes

Evaluating a novel, allosteric glucokinase activator in monogenic diabetes secondary to inactivating glucokinase mutations: a randomised, cross-over trial

Screening and Molecular Diagnosis-based Individualized Precision Management of Monogenic Diabetes

The goal of this observational study is to establish a registry, screening, and individualized management platform for patients with monogenic diabetes mellitus(MDM) using internet-based and mobile application software. The main questions it aims to answer are: * What are the genetic mutations causing MDM in China (genetic landscape)? * How effective and safe is the individualized, molecular-diagnosis-based management platform for MDM in improving patient outcomes? Participants will: * Register in the MDM platform via mobile app or internet-based software * Undergo genetic screening for MDM diagnosis * Participate in follow-up visits for individualized management and monitoring of blood glucose control and outcomes

Monogenic Diabetes Misdiagnosed as Type 1

The study has two aims: 1. To (1a) determine the frequency of monogenic diabetes misdiagnosed as type 1 diabetes (T1D) and (2) to define an algorithm for case selection. 2. To discover novel genes whose mutations cause monogenic diabetes misdiagnosed as T1D.

Identifying Maturity-onset Diabetes of the Young in Emirati Patients

Diabetes Mellitus is a disease that affects nearly 1 in 5 people in United Arab Emirates and is one of leading causes of death and disability. The main reason for this condition is either relative or near complete deficiency of essential hormone made by our pancreas called "insulin", which is required to utilize blood sugar (glucose), and insulin shortage leads to increased blood glucose. The common types of this condition include type 2 Diabetes Mellitus (the most common with almost 90% of all diabetes patients having this condition), which is related to mismatch of body requirements and production of essential hormone called insulin (relative deficiency) and type 1 diabetes, in which body's own defense system causes of destruction of insulin producing cells in the pancreas (near complete deficiency of insulin). However, in younger age group (below the age of 35) there is another type of diabetes which affects nearly 1 out 1000 people and is Maturity onset diabetes of the young (MODY). MODY is a condition passed by parents in 50% of the kids due to an affected single gene and most common forms of MODY do not require any Insulin treatment. However as type 1 Diabetes is generally identified in younger age group, 80% of patient who have MODY cannot be diagnosed and are labelled with other forms of diabetes instead, and may receive unnecessary insulin injections. Although, there has been a lot of research done in the west on prevalence of MODY in white/Caucasian population, the studies in Middle East are minimal. Also, in the white/Caucasian population, a reliable risk calculator has been developed that predicts the risk of having MODY, which if found to be high, is then confirmed by genetic testing for MODY. There is no study available on presence of MODY or on the reliability of the MODY risk calculator among young Emirati population. There is also no data on MODY being misdiagnosed as other forms of diabetes in Emirati population. This study proposal aims to address this gap of knowledge and assess the reliability of MODY calculator in young Emirati patients with diabetes and to see if any MODY patient exist in Diabetes clinics of Tawam hospital Abu Dhabi, who may have been misdiagnosed as type 1 or type 2.
