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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2023The c.781C>T (p.R261C) alteration is located in exon 7 (coding exon 7) of the GLP2R gene. This alteration results from a C to T substitution at nucleotide position 781, causing the arginine (R) at amino acid position 261 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
