Glimepiride is a medication taken by mouth that helps lower blood sugar levels in people with certain types of diabetes. In this study, it is being used to see how increasing the amount of this medicine affects blood sugar control in people with specific genetic forms of diabetes.

Maturity-onset diabetes of the young type 3 (HNF1A-MODY) – This is a genetic condition that affects how the body regulates blood sugar. It is caused by a mutation in a specific gene that helps control insulin production. The condition typically appears in young adulthood and involves a gradual decline in the ability of the pancreas to release enough insulin. As the disease progresses, blood sugar levels become increasingly difficult to maintain within a normal range.

Maturity-onset diabetes of the young type 1 (HNF4A-MODY) – This is a rare form of diabetes caused by a mutation in a gene responsible for regulating pancreatic function. It leads to a progressive reduction in the secretion of insulin by the pancreas. The condition often presents in younger individuals and results in rising blood sugar levels over time. As the disease advances, the body’s natural ability to manage glucose levels diminishes.
