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 GeneticsDec 13, 2023The c.162G>A (p.M54I) alteration is located in exon 2 (coding exon 2) of the GPRC5C gene. This alteration results from a G to A substitution at nucleotide position 162, causing the methionine (M) at amino acid position 54 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
