Genes affected

GPR27 (HGNC:4482): (G protein-coupled receptor 27) GPR27 is a member of the G protein-coupled receptors (GPCRs), a large family of receptors that have a similar structure characterized by 7 transmembrane domains. Activation of GPCRs by extracellular stimuli such as neurotransmitters, hormones, or light induces an intracellular signaling cascade mediated by heterotrimeric GTP-binding proteins, or G proteins.[supplied by OMIM, May 2010]

GPR27 links:

EIF4E3 (HGNC:31837): (eukaryotic translation initiation factor 4E family member 3) EIF4E3 belongs to the EIF4E family of translational initiation factors that interact with the 5-prime cap structure of mRNA and recruit mRNA to the ribosome (Joshi et al., 2004 [PubMed 15153109]).[supplied by OMIM, Mar 2008]

The c.495C>G (p.D165E) alteration is located in exon 1 (coding exon 1) of the GPR27 gene. This alteration results from a C to G substitution at nucleotide position 495, causing the aspartic acid (D) at amino acid position 165 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
