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]

The c.443G>A (p.C148Y) alteration is located in exon 5 (coding exon 4) of the GIP gene. This alteration results from a G to A substitution at nucleotide position 443, causing the cysteine (C) at amino acid position 148 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
