Genes affected

GPR174 (HGNC:30245): (G protein-coupled receptor 174) This gene encodes a protein belonging to the G protein-coupled receptor superfamily. These proteins are characterized by the presence of seven alpha-helical transmembrane domains, and they activate or interact with various endogenous or exogenous ligands, including neurotransmitters, hormones, and odorant and taste substances. This family member is classified as an orphan receptor because the cognate ligand has not been identified. [provided by RefSeq, Sep 2011]

The c.553A>G (p.M185V) alteration is located in exon 1 (coding exon 1) of the GPR174 gene. This alteration results from a A to G substitution at nucleotide position 553, causing the methionine (M) at amino acid position 185 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
