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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 09, 2024The c.875T>A (p.I292N) alteration is located in exon 2 (coding exon 1) of the GPR3 gene. This alteration results from a T to A substitution at nucleotide position 875, causing the isoleucine (I) at amino acid position 292 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
