Pharmacogenetics of Glucagon-like-peptide-1 receptor in diabetes management

Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder, primarily characterized by a decrease in insulin secretion and typically accompanied by insulin resistance. When untreated, T2DM is leading to an inevitable long-term complication. However, the novel treatment of T2DM like for example Glucagon-like Peptide-1 receptor agonists (GLP-1 RAs) give new perspectives for the patients to achieve a better glycemic control and additional metabolic improvements. Pharmacogenetics is a field in pharmacotherapy, which investigates the individual response to the medical treatment, according to polymorphic variations in the receptors of the drugs. This review aims to summarize current scientific evidence on the pharmacogenetics of the GLP-1 RA /liraglutide/ and the possible implementation in the treatment of T2D.
