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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2023The c.884C>T (p.A295V) 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 884, causing the alanine (A) at amino acid position 295 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
