Genes affected
GPR39 (HGNC:4496): (G protein-coupled receptor 39) This gene is a member of the ghrelin receptor family and encodes a rhodopsin-type G-protein-coupled receptor (GPCR). The encoded protein is involved in zinc-dependent signaling in epithelial tissue in intestines, prostate and salivary glands. The protein may also be involved in the pathophysiology of depression.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.436G>A (p.V146M) alteration is located in exon 1 (coding exon 1) of the GPR39 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the valine (V) at amino acid position 146 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
