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]

The c.244T>C (p.F82L) alteration is located in exon 2 (coding exon 2) of the GPR139 gene. This alteration results from a T to C substitution at nucleotide position 244, causing the phenylalanine (F) at amino acid position 82 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
