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.

The c.332T>C (p.F111S) alteration is located in exon 2 (coding exon 1) of the GPRC5B gene. This alteration results from a T to C substitution at nucleotide position 332, causing the phenylalanine (F) at amino acid position 111 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
