Genes affected

GLP2R (HGNC:4325): (glucagon like peptide 2 receptor) This gene encodes a G protein-coupled receptor that is closely related to the glucagon receptor and binds to glucagon-like peptide-2 (GLP2). Signalling through GLP2 stimulates intestinal growth and increases villus height in the small intestine, concomitant with increased crypt cell proliferation and decreased enterocyte apoptosis.

Ambry Genetics

Feb 28, 2023

The c.964C>T (p.R322C) alteration is located in exon 8 (coding exon 8) of the GLP2R gene. This alteration results from a C to T substitution at nucleotide position 964, causing the arginine (R) at amino acid position 322 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
