Genes affected
GPRC5C (HGNC:13309): (G protein-coupled receptor class C group 5 member C) The protein encoded by this gene is a member of the type 3 G protein-coupled receptor family. Members of this superfamily are characterized by a signature 7-transmembrane domain motif. The specific function of this protein is unknown; however, this protein may mediate the cellular effects of retinoic acid on the G protein signal transduction cascade. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.877A>G (p.T293A) alteration is located in exon 2 (coding exon 2) of the GPRC5C gene. This alteration results from a A to G substitution at nucleotide position 877, causing the threonine (T) at amino acid position 293 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
