Genes affected

GPR119 (HGNC:19060): (G protein-coupled receptor 119) This gene encodes a member of the rhodopsin subfamily of G-protein-coupled receptors that is expressed in the pancreas and gastrointestinal tract. The encoded protein is activated by lipid amides including lysophosphatidylcholine and oleoylethanolamide and may be involved in glucose homeostasis. This protein is a potential drug target in the treatment of type 2 diabetes.[provided by RefSeq, Jan 2010]

Dec 28, 2022

The c.815C>A (p.S272Y) alteration is located in exon 1 (coding exon 1) of the GPR119 gene. This alteration results from a C to A substitution at nucleotide position 815, causing the serine (S) at amino acid position 272 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
