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.

The c.706C>T (p.L236F) alteration is located in exon 1 (coding exon 1) of the GPR39 gene. This alteration results from a C to T substitution at nucleotide position 706, causing the leucine (L) at amino acid position 236 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
