Genes affected

GPRC6A (HGNC:18510): (G protein-coupled receptor class C group 6 member A) Members of family C of the G protein-coupled receptor (GPCR) superfamily, such as GPRC6A, are characterized by an evolutionarily conserved amino acid-sensing motif linked to an intramembranous 7-transmembrane loop region. Several members of GPCR family C, including GPRC6A, also have a long N-terminal domain (summary by Pi et al., 2005 [PubMed 16199532]).[supplied by OMIM, Nov 2010]

Ambry Genetics

Sep 27, 2021

The c.1882G>A (p.G628R) alteration is located in exon 6 (coding exon 6) of the GPRC6A gene. This alteration results from a G to A substitution at nucleotide position 1882, causing the glycine (G) at amino acid position 628 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
