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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.2520G>C (p.K840N) alteration is located in exon 6 (coding exon 6) of the GPRC6A gene. This alteration results from a G to C substitution at nucleotide position 2520, causing the lysine (K) at amino acid position 840 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
