Genes affected

ADGRG4 (HGNC:18992): (adhesion G protein-coupled receptor G4) This gene encodes a G-protein coupled receptor belonging to a large family of diverse integral membrane proteins that participate in various physiological functions. Members of this superfamily are characterized by a signature 7-transmembrane domain motif. The ligand for this family member is unknown, and it is therefore an orphan receptor. This receptor is known to be expressed in normal enterochromaffin cells and in gastrointestinal neuroendocrine carcinoma cells, and it is therefore considered to be a novel biomarker or target for immunotherapy.

Ambry Genetics

Nov 21, 2022

The c.583G>A (p.E195K) alteration is located in exon 5 (coding exon 2) of the ADGRG4 gene. This alteration results from a G to A substitution at nucleotide position 583, causing the glutamic acid (E) at amino acid position 195 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
