Genes affected

ADGRG2 (HGNC:4516): (adhesion G protein-coupled receptor G2) This gene encodes a member of the G protein-coupled receptor family described as an epididymis-specific transmembrane protein. The encoded protein may be proteolytically processed as it contains a motif shown to be a protein scission motif in some members of this family (PMID: 11973329). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

The c.2704G>A (p.A902T) alteration is located in exon 27 (coding exon 25) of the ADGRG2 gene. This alteration results from a G to A substitution at nucleotide position 2704, causing the alanine (A) at amino acid position 902 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
