GLP1R
protein-codingglucagon like peptide 1 receptor, the group of Glucagon receptor family
Gene summary
This gene encodes a 7-transmembrane receptor for glucagon-like peptide 1 (GLP-1), which stimulates glucose-dependent insulin secretion. The receptor, located on the cell surface, is internalized upon ligand binding and triggers signaling pathways that regulate insulin release, appetite, gastric emptying, and energy balance. It also has neuroprotective and cardiovascular effects. Polymorphisms in this gene are linked to type 2 diabetes risk, and the receptor is a key drug target for diabetes, obesity, and stroke therapies. [provided by RefSeq, Mar 2026]

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_002062.5. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
