Genes affected

GIP (HGNC:4270): (gastric inhibitory polypeptide) This gene encodes an incretin hormone and belongs to the glucagon superfamily. The encoded protein is important in maintaining glucose homeostasis as it is a potent stimulator of insulin secretion from pancreatic beta-cells following food ingestion and nutrient absorption. This gene stimulates insulin secretion via its G protein-coupled receptor activation of adenylyl cyclase and other signal transduction pathways. It is a relatively poor inhibitor of gastric acid secretion. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 28, 2023

The c.448C>G (p.L150V) alteration is located in exon 5 (coding exon 4) of the GIP gene. This alteration results from a C to G substitution at nucleotide position 448, causing the leucine (L) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
