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.1193C>T (p.T398I) alteration is located in exon 4 (coding exon 3) of the GPRC5B gene. This alteration results from a C to T substitution at nucleotide position 1193, causing the threonine (T) at amino acid position 398 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
