Genes affected

GPR3 (HGNC:4484): (G protein-coupled receptor 3) This gene is a member of the G protein-coupled receptor family and is found in the cell membrane. G protein-coupled receptors, characterized by a seven transmembrane domain motif, are involved in translating outside signals into G protein mediated intracellular effects. The encoded protein activates adenylate cyclase and modulates amyloid-beta production in a mouse model, suggesting that it may play a role in Alzheimer's disease. [provided by RefSeq, Oct 2012]

The c.911T>C (p.V304A) alteration is located in exon 2 (coding exon 1) of the GPR3 gene. This alteration results from a T to C substitution at nucleotide position 911, causing the valine (V) at amino acid position 304 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
