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

Feb 13, 2024

The c.1916G>A (p.C639Y) 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 1916, causing the cysteine (C) at amino acid position 639 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
