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 GeneticsNov 19, 2022The c.1093C>T (p.R365W) alteration is located in exon 2 (coding exon 2) of the GPRC5C gene. This alteration results from a C to T substitution at nucleotide position 1093, causing the arginine (R) at amino acid position 365 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
