Genes affected
GPRC5B (HGNC:13308): (G protein-coupled receptor class C group 5 member B) This gene encodes 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 encoded protein may modulate insulin secretion and increased protein expression is associated with type 2 diabetes. Alternative splicing results in multiple transcript variants.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.464C>T (p.T155M) alteration is located in exon 2 (coding exon 1) of the GPRC5B gene. This alteration results from a C to T substitution at nucleotide position 464, causing the threonine (T) at amino acid position 155 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
