ABCC8 : ATP binding cassette subfamily C member 8

Understanding the ABCC8 Gene: A Gatekeeper of Insulin Secretion

Description:

The ABCC8 gene plays a crucial role in regulating blood sugar levels by encoding the SUR1 protein, a key component of the ATP-sensitive potassium (K-ATP) channels in pancreatic beta cells. These channels act as gatekeepers, controlling the release of insulin from beta cells into the bloodstream. Insulin, a vital hormone, facilitates the transport of glucose from the bloodstream into cells, maintaining energy homeostasis.

Associated Diseases:

Mutations in the ABCC8 gene have been linked to several conditions, including:

• Neonatal Diabetes: A rare form of diabetes that develops in newborns due to reduced insulin secretion.
• Type 2 Diabetes: In some cases, ABCC8 mutations can contribute to the development of type 2 diabetes by impairing insulin secretion.
• Congenital Hyperinsulinism: A condition characterized by excessive insulin production, often due to defects in K-ATP channel function.

Did you Know ?

Studies have shown that approximately 1 in 200 people with type 2 diabetes have a mutation in the ABCC8 gene.
