The goal of this observation is to establish a complete registry for the clinical manifestations, environment, genetic, and other related gene variation information of young-onset diabetic patients. Moreover, according to the physiological and pathological mechanisms of different genes, the impact on the clinical characteristics of diabetes, the therapeutic response to drugs, and the impact on complications will be analyzed.
The main questions are:
1. The distribution of different types of MODY
2. The phenotypes and clinical characteristics of different types of MODY
3. Response to antidiabetic drugs among different types of MODY
Once the participant is enrolled, their questionnaire information (including disease course and development, health history, family history, drug history, etc.), medication, outpatient/inpatient medical history, etc. will be collected and logged in. Blood and urine samples will also be collected for biochemical tests genetic testing, etc.
At the same time, the investigators will conduct a continuous follow-up on a regular basis (3 months, 6 months, 12 months, 24 months, and 5 years after the study subject is enrolled).
Young-onset type 2 diabetes will be compared to see the difference in clinical presentations and responses to antidiabetic drugs.
