Genes affected

GPR139 (HGNC:19995): (G protein-coupled receptor 139) This gene encodes a member of the rhodopsin family of G-protein-coupled receptors. The encoded protein is almost exclusively expressed in the central nervous system. L-tryptophan and L-phenylalanine may act as the physiologic ligands of the encoded protein. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Ambry Genetics

Dec 13, 2022

The c.613A>G (p.I205V) alteration is located in exon 2 (coding exon 2) of the GPR139 gene. This alteration results from a A to G substitution at nucleotide position 613, causing the isoleucine (I) at amino acid position 205 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
