Genes affected

GPR78 (HGNC:4528): (G protein-coupled receptor 78) The protein encoded by this gene belongs to the G protein-coupled receptor family, which contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins. This is an orphan receptor, which displays significant level of constitutive activity. Association analysis shows preliminary evidence for the involvement of this gene in susceptibility to bipolar affective disorder and schizophrenia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2011]

Sep 29, 2022

The c.7C>T (p.P3S) alteration is located in exon 1 (coding exon 1) of the GPR78 gene. This alteration results from a C to T substitution at nucleotide position 7, causing the proline (P) at amino acid position 3 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
