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 GeneticsJan 26, 2022The c.67G>A (p.E23K) alteration is located in exon 1 (coding exon 1) of the GLP2R gene. This alteration results from a G to A substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
