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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.267T>A (p.D89E) alteration is located in exon 2 (coding exon 2) of the GPR139 gene. This alteration results from a T to A substitution at nucleotide position 267, causing the aspartic acid (D) at amino acid position 89 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
